Detailed ways

In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

The suspension system mainly includes suspension brackets for connection and suspension cushions for vibration reduction. Among them, the suspension bracket is used to connect the body and the powertrain. Suspension cushions are used to dampen vibrations from the powertrain to the body, and from the body to the powertrain. The powertrain includes the transmission and engine.

Mounting system can be divided into three-point mounting and four-point mounting according to the layout. Among them, the three-point mount includes left mount, right mount and rear mount, and the four-point mount includes left mount, right mount, front mount and rear mount. Exemplarily, the front suspension is arranged on the subframe cross member, the rear suspension is arranged on the subframe or the body reinforcement, the left suspension is arranged on the left side member, and the right suspension is arranged on the right side member.

Usually, 28 mounting conditions are used to check whether the strength of the mounting is qualified. The 28 mounting conditions include typical mounting conditions and extreme mounting conditions.

Among them, the typical mounting conditions include: static design position (under the dead weight of the powertrain); the maximum forward torque of the engine; the maximum backward torque of the engine; the maximum forward torque of the engine and the forward acceleration of the front drive, the maximum forward torque of the engine and the forward acceleration of the rear drive, the engine Maximum forward torque and 4WD forward acceleration; Engine maximum forward torque and left transmission; Engine maximum forward torque and right transmission; Engine maximum forward torque and vertical downward shock; Engine maximum forward torque and vertical rebound; Engine maximum reverse torque and Front-drive reverse acceleration, engine maximum reverse torque and rear-drive reverse acceleration, engine maximum reverse torque and four-wheel drive reverse acceleration; bad road up; bad road down, forward longitudinal loading (full throttle acceleration); reverse longitudinal loading (full throttle acceleration) ; 1x gravity load; part forward torque (5/8 full throttle); part reverse torque.

The ultimate suspension conditions include: 8KPH front impact; 8KPH rear impact; vertical upward loading (deep pit); vertical downward loading (deep pit); lateral loading to the left; lateral loading to the right; vertical upward and lateral left loading; Vertical up and lateral right loading; vertical down and lateral left loading; vertical down and lateral right loading; full throttle N to D (clutch resists full throttle combined); full throttle N to R (clutch reverse full throttle combination).

Among the 28 mounting conditions, each mounting condition corresponds to a three-direction load (FX, FY, FZ). FX is the load in the first direction, FY is the load in the second direction, and FZ is the load in the third direction. The first direction, the second direction and the third direction are perpendicular to each other.

When 28 mounting conditions are used to check the strength of the mount, since each mounting condition corresponds to the load in three directions, and when checking the strength of the mount, it is necessary to check the body side mount (the mount connected to the chassis of the vehicle). One side) and the power main side mount (the side where the mount is connected to the engine or gearbox) are checked for strength separately. When engineers check the strength of the mount in the mount analysis software, they need to check the strength of each mount under each mounting condition. Three-directional loads are applied one by one. Taking the three-point mount as an example, to complete a round of analysis of 28 mounting conditions, engineers need to manually set the mounting conditions 504 times.

Therefore, the embodiments of the present disclosure provide a suspension strength inspection method, which reduces the workload of manual operations, avoids possible loading errors caused by human negligence in the loading process, and facilitates engineers to devote more energy to Interpretation of post-processing results and optimization and improvement of suspension structures.

The specific selection of the target mounting conditions shall be determined by the relevant technical personnel according to the actual inspection needs. For example, the target mount case is 28 mount cases.

In step 102, a target load corresponding to the target mounting condition is determined according to the corresponding relationship between the mounting condition and the load.

In the corresponding relationship, each mounting condition includes loads in the first direction, the second direction and the third direction. The first direction, the second direction and the third direction are perpendicular to each other. Different mounting conditions correspond to different loads.

In some examples, a correspondence between suspension conditions and loads is stored in the computer device. The computer equipment can determine the load corresponding to the target mounting condition according to the target mounting condition and the corresponding relationship between the mounting condition and the load.

In step 103, target loads are loaded to the plurality of sub-mount models of the mount model to obtain inspection results.

Exemplarily, the mount model is the aforementioned three-point mount model or four-point mount model.

The inspection result is used to indicate the eligibility of the strength of the mount model under the target mount condition.

Exemplarily, the computer device may automatically load loads corresponding to the target mounting condition to multiple sub-mounting models of the mounting model, and obtain inspection results of the mounting model under the target mounting condition.

In step 104, the inspection result is output.

In some examples, the computer device outputs the inspection results to a display device to present the inspection results through the display device. In other examples, the computer device outputs the inspection result to a storage device to save the inspection result through the storage device.

In the embodiment of the present disclosure, the working condition indication information is obtained first, and the working condition indication information is used to indicate the target mounting condition; then, the target load corresponding to the target mounting condition is determined according to the corresponding relationship between the mounting condition and the load ; Finally, load the target load to the multiple sub-mount models of the mount model to obtain the inspection result, and the inspection result is used to indicate the qualification of the strength of the mount model under the target mount condition. In this process, only the working condition indication information needs to be input, and the target mounting condition determined by the corresponding relationship between the mounting working condition and the load and the working condition indication information can be used to determine the target load, and then complete the strength inspection of the mount. . This process does not require manual input of multiple loads for each sub-mount model under the target mounting condition, thereby improving the efficiency of the strength inspection of the mount.

FIG. 2 is a flowchart of a method for checking the strength of a suspension provided by an embodiment of the present disclosure, and the method may be executed by a computer device. Referring to Figure 2, the method includes:

The multiple sub-mounting models corresponding to the four-point mounting model include a front mounting sub-model, a rear mounting sub-model, a left mounting sub-model and a right mounting sub-model.

The multiple components corresponding to the rear suspension sub-model (right side) include a third moving main side bracket, a fourth moving main side bracket and two second subframe side brackets.

In some embodiments, the suspension model is automatically generated by a computer device. Step 201 includes the following steps:

The first step is to obtain model parameters and constraint node parameters of multiple sub-mount models of the mount model.

In some examples, the model parameters of the sub-suspension model are the model numbers of the multiple components of the sub-suspension model, or the structural dimension parameters of the multiple components of the sub-suspension model.

In some examples, the constraint node parameters of the sub-mount model are the number of mounting bolt holes and the positions of the mounting bolt holes of the sub-mount model. Here, the mounting bolt holes refer to the bolt holes connecting the sub-mount models with the vehicle body side, the power train side or the gearbox, excluding the bolt holes between the sub-mount models. For example, the left suspension submodel includes three suspension bolt holes that connect to the gearbox, and three suspension bolt holes that connect to the body side.

Exemplarily, the computer device stores model parameters and constraint node parameters of a plurality of sub-suspension models corresponding to the suspension model. The computer device may acquire the model parameters and constraint node parameters of the plurality of sub-suspension models corresponding to the stored suspension model from the storage device.

In the second step, multiple sub-mount models are generated according to the model parameters of the multiple sub-mount models.

Exemplarily, the computer device may automatically generate the corresponding sub-mount model according to the model parameters of each sub-mount model.

In the third step, a suspension model is generated according to the plurality of sub-suspension models and the constraint node parameters of the plurality of sub-suspension models.

Exemplarily, the computer device may fix the sub-mount model between the vehicle body side and the powertrain side according to the generated sub-mount model and the acquired constraint node parameters of the sub-mount model, thereby obtaining the mount model.

Optionally, the first step and the second step may also be replaced by: acquiring multiple sub-suspension models corresponding to the suspension model and constraint node parameters corresponding to the multiple sub-suspension models.

In this example, multiple sub-suspension models corresponding to the suspension model are stored in the computer device, and the multiple sub-suspension models corresponding to the suspension model can be directly acquired from the storage device.

In other embodiments, the suspension model is stored in a storage unit of the computer device. The computer equipment can obtain the suspension model directly from the storage unit.

In step 202, working condition indication information is obtained, and the working condition indication information is used to indicate the target suspension working condition.

For the relevant content of the target suspension working condition, refer to the foregoing step 101, and the detailed description is omitted here.

In the embodiment of the present disclosure, any one of the following methods may be used to obtain the working condition indication information:

The first way is to receive the input identification of the target suspension working condition. The working condition indication information is the identification of the target suspension working condition.

In some examples, the identification of 28 suspension conditions is stored in the computer device. The identification of each mounting condition corresponds to one of the 28 mounting conditions, and the identifications of different mounting conditions correspond to different mounting conditions. The identification of the suspension condition can be numbers or characters, etc. Exemplarily, numbers 1 to 28 correspond to 28 mounting conditions, respectively.

The relevant skilled person can input the identification of the target suspension working condition in the computer equipment. The computer equipment determines the target suspension condition according to the identification of the target suspension condition input by the relevant technical personnel.

In a second manner, the working condition indication information is obtained according to the selection instruction input based on the suspension working condition list.

In some examples, the list of mounting conditions includes the aforementioned 28 mounting conditions, and a selection box corresponding to each mounting condition.

A list of suspension conditions is displayed on the display interface of the computer equipment. The selection instruction is triggered by the relevant technical personnel clicking at least one selection box in the suspension condition list. The selection command includes operating condition indication information. After the computer device obtains the selection instruction, it can determine the corresponding target mounting condition.

Mode 3: Receive the identifier of the input sub-mount model, and based on the preset correspondence between the sub-mount model and the mounting condition and the identifier of the sub-mount model, assign the mount tool corresponding to the identifier of the sub-mount model. condition as the target suspension condition.

Among multiple sub-mount models of a mount model, the mounting conditions to be loaded for each sub-mount model may be different. In some examples, the computer device stores the mounting conditions to which the sub-mounting model needs to be loaded. The computer equipment can determine the corresponding sub-mount model and the target mounting condition corresponding to the sub-mount model according to the identifier of the sub-mount model input by the relevant technician.

In step 203, a target load corresponding to the target mounting condition is determined according to the corresponding relationship between the mounting condition and the load.

For the corresponding relationship and the content related to determining the target load corresponding to the target suspension working condition, refer to the foregoing step 102, and the detailed description is omitted here.

In step 204, the elastic center point coordinates of the sub-suspension model are determined.

The elastic center point refers to the center position where the body side and the dynamic main side of the sub-suspension are connected by the bushing.

Exemplarily, the elastic center point coordinates of each sub-suspension model are stored in the computer device. The computer device can acquire the elastic center point coordinates of each sub-suspension model from the storage unit.

In step 205, a target load is loaded at the position corresponding to the coordinates of the elastic center point of the sub-mount model.

In some embodiments, step 205 includes: sequentially loading the loads in the first direction, the second direction and the third direction corresponding to the target suspension condition at the position corresponding to the elastic center point coordinates of the sub-suspension model.

It should be noted that, in the embodiment of the present disclosure, when the computer device loads the target load to the multiple sub-mount models of the mount model, it can only load the load of one mount condition in one direction at a time. For example, the corresponding loads in the first direction, the second direction and the third direction under the condition of the maximum forward torque of the engine are (Fx1, Fy1, Fz1), and the computer equipment can only load the loads in the first direction under the mounting condition at a time. The load Fx1, or the load Fy1 in the second direction under the suspension condition, or the load Fz1 in the third direction under the suspension condition is loaded.

In step 206, the inspection result is output.

The inspection result is used to indicate the eligibility of the strength of the mount model under the target mount condition. Illustratively, the inspection results are in the form of a table.

In some examples, the inspection results include only the stresses of the multiple components of the target submount model under the target mount conditions.

In other examples, the inspection results include only the eligibility of the multiple components of the target submount model under the target mount conditions.

In yet other examples, the inspection results include the stress of the plurality of components of the target submount model under the target mount conditions, and the eligibility of each component.

Exemplarily, the stress threshold of each component corresponding to each sub-suspension model is stored in the computer device. After the computer equipment loads the sub-mount model with the load corresponding to the target mount condition, it will automatically calculate the stress of the multiple components of the sub-mount model under the target mount condition. When the stress exceeds the stress threshold corresponding to the component, the strength of the component is judged to be unqualified; when the stress does not exceed the stress threshold corresponding to the component, the strength of the component is judged to be qualified.

In some embodiments, step 206 includes: receiving suspension indication information; and outputting inspection results based on the suspension indication information.

The suspension indication information is used to indicate the target sub-suspension model and/or the target component. For example, the suspension indication information is used to indicate the target sub-suspension model; alternatively, the suspension indication information is used to indicate the target component; or the suspension indication information is used to indicate the target sub-suspension model and the target component.

The target sub-suspension model is at least one of a plurality of sub-suspension models of the suspension model. The target component is at least one of a plurality of components of the target sub-suspension model. For the related content of the components of the sub-suspension model, refer to the foregoing step 201, and the detailed description is omitted here.

In some implementations, the suspension indication information includes an identification of the target sub-suspension model and an identification of the target component. Based on the suspension indication information, output the inspection result, including: outputting the inspection result of the target component under the target suspension condition.

In this embodiment, the identifiers of the components in the same sub-suspension model are different, and the identifiers of the components corresponding to different sub-suspension models may be the same or different. Therefore, the target component can be determined according to the identification of the target sub-mount model and the identification of the target component. Illustratively, the sub-suspension models are identified by letters, such as a, b, c, etc.; the components are identified by numbers, such as 1, 2, 3, and so on.

Illustratively, the identification of the target sub-suspension model and the identification of the target component are input into the computer device by the relevant skilled person. After acquiring the identification of the target sub-mount and the identification of the target component input by the relevant technician, the computer device outputs the corresponding inspection result of the target component under the working condition of the target mount.

In this embodiment, the relevant technical personnel can directly obtain the inspection result of the target component under the target suspension working condition according to the identification of the sub-mount model and the identification of the component corresponding to the sub-mount model, which saves the inspection of the relevant technical personnel. Result processing time.

In other embodiments, the suspension indication information includes an identification of the target component. Based on the suspension indication information, output the inspection result, including: outputting the inspection result of the target component under the target suspension condition.

In this embodiment, the identifiers of the components corresponding to different sub-suspension models are different. Therefore, only based on the identification of the target component, a unique target component can be determined.

Illustratively, the identification of the target component is entered into the computer device by the relevant skilled person. After acquiring the identification of the target component input by the relevant technician, the computer device outputs the corresponding inspection result of the target component under the target suspension condition.

In this embodiment, the relevant technical personnel can directly obtain the inspection result of the component under the target suspension working condition according to the identification of the component corresponding to the sub-mount model, which saves the relevant technical personnel's processing time of the inspection result.
