Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
The suspension system mainly comprises a suspension bracket for connection and a suspension cushion for vibration reduction. The suspension bracket is used for connecting the vehicle body and the power assembly. The suspension cushions are used to dampen powertrain to body vibrations, as well as vehicle body to powertrain vibrations. The power assembly comprises a gearbox and an engine.
The suspension system may be classified into a three-point suspension, a four-point suspension, and the like according to the arrangement manner. The three-point suspension comprises a left suspension, a right suspension and a rear suspension, and the four-point suspension comprises a left suspension, a right suspension, a front suspension and a rear suspension. Illustratively, the front suspension is arranged on a subframe cross beam, the rear suspension is arranged on a subframe or a vehicle body reinforcing plate, the left suspension is arranged on a left longitudinal beam, and the right suspension is arranged on a right longitudinal beam.
Typically, 28 suspension conditions are used to check the strength of the suspension. The 28 suspension conditions include typical suspension conditions and extreme suspension conditions.
Wherein, typical suspension operating mode includes: static design position (under the weight of the powertrain); engine maximum forward torque; maximum engine torque backing off; the engine maximum forward torque and the forward drive forward acceleration, the engine maximum forward torque and the rear drive forward acceleration, the engine maximum forward torque and the four-wheel drive forward acceleration; maximum forward torque and left transmission of the engine; the maximum forward torque and the right transmission of the engine; maximum forward torque and vertical downward impact of the engine; maximum forward torque and vertical rebound of the engine; the engine maximum backward torque and forward drive backward acceleration, the engine maximum backward torque and backward drive backward acceleration, the engine maximum backward torque and four-wheel drive backward acceleration; the bad way is upward; loading downwards and longitudinally in a forward direction on a bad road (full accelerator acceleration); reverse longitudinal loading (full throttle acceleration); 1 time gravity acceleration load; partial forward torque (5/8 full throttle); and (5) partial reverse gear torque.
The limit suspension working conditions comprise: 8KPH front collision; 8KPH back collision; vertical upward loading (pit); vertical downward loading (pit); loading transversely leftwards; loading to the right in a transverse direction; loading vertically up and laterally left; loading vertically up and laterally right; loading vertically down and laterally left; vertical downward and lateral rightward loading; full throttle N to D (clutch against full throttle combination); full throttle N to R (clutch reverse full throttle combination).
In 28 suspension conditions, each suspension condition corresponds to a three-directional load (FX, FY, FZ). FX is a load in the first direction, FY is a load in the second direction, and FZ is a load in the third direction. The first direction, the second direction and the third direction are vertical to each other.
When the strength of the suspension is checked by adopting 28 suspension working conditions, because each suspension working condition corresponds to the load in three directions, and when the suspension strength is checked, the strength of the vehicle body side suspension (one side of the suspension connected with a vehicle chassis) and the dynamic main side suspension (one side of the suspension connected with an engine or a gearbox) need to be checked respectively, and when an engineer checks the strength of the suspension in suspension analysis software, the three-direction loads under each suspension working condition need to be applied one by one. For example, in a three-point suspension, an engineer needs to manually set the suspension conditions 504 times to complete the analysis of 28 suspension conditions in one round.
Therefore, the embodiment of the disclosure provides a method for checking the strength of a suspension, which reduces the workload of manual operation, avoids possible loading errors caused by human negligence in the loading process, and is convenient for engineers to put more energy into the interpretation of the post-processing result and the optimization and improvement of the suspension structure.

The computer equipment can determine the load corresponding to the target suspension working condition according to the target suspension working condition and the corresponding relation between the suspension working condition and the load.
In step 103, target loads are loaded to a plurality of sub-suspension models of the suspension model to obtain inspection results.

And the computer equipment determines the target suspension working condition according to the identification of the target suspension working condition input by the related technical personnel.
And in the second mode, working condition indication information is obtained according to a selection instruction input based on the suspension working condition list.
