The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
The embodiment provides a method for testing a stress value of a workpiece, as shown in fig. 1, the method includes:
The first stress value is the stress value at the target position of the workpiece to be tested, and the second stress value is the stress value at the position corresponding to the target position on the simulated workpiece.
The load conditions specifically include: the stress testing device comprises a force application position, a force application direction and different force application values, and stress values of a workpiece to be tested under the conditions of acting forces such as tensile force, pressure and extrusion force can be tested by setting different load conditions.
Fig. 2 shows a simplified diagram of a physical test of a workpiece to be tested, in which forces F are applied to a first position and a second position of the workpiece to be tested 1 to apply a pressing force to the workpiece to be tested, and a sensor 2 is arranged at a target position to test a stress value to which the workpiece to be tested is subjected. In particular, the sensor 2 acquires the forces F applied at a first position and at a second position, respectively, of the workpiece 1 to be tested1、F2,…,FkIn the case of (2), the corresponding first stress value σ experienced1、σ2,…,σk。
In this embodiment, the difference between the applied forces is obtained according to the actual situation (for example, the target value may be set as the maximum value of the force allowed by the actual working condition) and divided by the k value, where the k value may be selected according to the actual situation, and when the k value is larger, the finally obtained detection data is more accurate.
Similarly, a simulated workpiece to be subjected to data simulation processing on the test workpiece is obtained, the simulated load condition identical to the load condition is set, and simulation analysis calculation is carried out, so that the stress value sigma of the position corresponding to the target position on the simulated workpiece can be obtained1'、σ2',…,σk'。
And 102, acquiring a deviation value of the first stress value and the second stress value.
Since there may be a deviation between the simulated second stress value and the first stress value detected by the real object, in this embodiment, a deviation value of the simulated second stress value and the first stress value under each stress condition is obtained, for example, when the applied force is F1While, the deviation value is σ1-σ1', when the applied force is FkWhile, the deviation value is σk-σk', several sets of applied force and bias value combinations can ultimately be obtained, [ F ]1,(σ1-σ1')]，[F2,(σ2-σ2')]，[F3,(σ3-σ3')],…,[Fk,(σk-σk')]。
And 103, constructing a target equation according to the load condition and the corresponding deviation value.
According to the sets of deviation values and load conditions obtained in step 102, a least square function can be used for modeling to construct a linear regression equation, i.e., a target equation, wherein the target equation is used for representing the relationship between the load conditions and the deviation values, and it should be understood that when the number of k is large, i.e., the number of different forces to be tested is large, according to the linear regression principle, the influence on the accuracy of the whole equation due to the large error of a certain value can be avoided to a great extent, and thus a more accurate equation can be obtained.
And 104, acquiring target load conditions, and acquiring corresponding target deviation values according to a target equation.
And 105, acquiring a target second stress value of the simulation workpiece under the target load condition.
And 106, acquiring a target first stress value according to the target second stress value and the target deviation value.
When the force required to be tested is FnAt a first stress value of (wherein, F)nMay exceed the maximum limit of the current test equipment), the test equipment cannot meet the test conditions, or the field test is inconvenient to be carried out, the simulation test result sigma obtained by the pure simulation analysis datan' there is an unavoidable error, and in this case, the force F applied can be determined from the target equationn(even if the target load condition is Fn) Deviation value (sigma) of time responsen-σn') based thereon, a target first stress value of the corresponding physical test can be predicted, i.e. sigman'+(σn-σn')。
In this embodiment, a target equation may be obtained according to the load condition and the deviation value of the first stress value of the workpiece to be tested under the corresponding load condition and the second stress value of the corresponding simulated workpiece, when the stress value of the workpiece to be tested needs to be detected, a target deviation value may be obtained by inputting the target load condition to the target equation, and an accurate stress value of the actual workpiece, that is, a target first stress value, may be effectively obtained according to the target deviation value and the target simulated stress value obtained under the target load condition.
In the embodiment, after the target equation is obtained, the data detection can be carried out on line without carrying out physical detection, so that the detection cost is reduced; and based on the collected physical test data and simulation data, the physical test data is used for correcting the simulation data to obtain a target equation, the result of the simulated stress value can be corrected, the physical detection stress value can be accurately predicted, and even under the condition that the test equipment cannot meet the test conditions (such as the condition that enough applied force cannot be provided, the on-site detection cannot be carried out and the like), the stress value of the workpiece to be tested can still be efficiently detected.
In a preferred real-time mode, as shown in fig. 3, step 101 further includes:
and 112, taking the position of which the third stress value is greater than the first threshold value as a target detection position.
The first threshold may be set according to actual conditions, and if a plurality of target detection positions are obtained, a target mode may be established for each detection position in the manner of steps 101 to 103, and stress value prediction may be performed on the corresponding target detection position in the manner of steps 104 to 106.
In the case of an unstressed workpiece, i.e. in the safest state of the workpiece, the stress value is 0 everywhere on the workpiece. In the case of stress on the workpiece, the greater the stress value, the more likely the risk of failure to meet the standard, yielding, breaking, etc. occurs, therefore, in this embodiment, when a physical test is performed on the workpiece to be tested, a simulation analysis result is obtained in a simulation manner, which is similar to a "pre-test", a target position at which the risk easily occurs can be approximately obtained, and based on this, physical detection can be guided, and the target position of the physical object is taken as the position for detecting the stress value.
In a preferred real-time mode, step 106 is followed by:
and step 107, when the target stress value exceeds a second threshold value, generating prompt information.
Wherein the target stress value comprises a target first stress value or a target stress value.
In this embodiment, the second threshold may be set according to an actual situation, and when it is predicted that the target first stress value of the workpiece to be tested exceeds the second threshold, it is described that the workpiece to be tested may be subjected to dangers such as yielding, breaking and the like, so that prompt information is generated to remind related personnel of handling.
Because the load conditions that different materials can bear may be different, in a specific embodiment, the corresponding second threshold may be obtained according to the material of the workpiece to be tested, specifically, the second threshold corresponding to each material is preset in the background, the second threshold corresponding to the material of the workpiece to be tested may be obtained before step 107, and in step 107, the corresponding second threshold may be compared with the target first stress value.
In a preferred embodiment, the second threshold includes a standard threshold, a yield threshold and a fracture threshold, and the standard threshold is less than the yield threshold and the yield threshold is less than the fracture threshold. Specifically, the standard threshold, the yield threshold and the fracture threshold corresponding to different materials may be stored in the background, and similarly, the corresponding thresholds may be obtained before step 107.
Step 107 may specifically include the following steps:
when the target stress value exceeds a standard threshold value, generating prompt information for indicating that the workpiece to be tested has a risk of not meeting a preset detection standard;
when the target stress value exceeds the yield threshold value, prompt information for indicating that the workpiece to be tested has plastic deformation risk is generated
And when the target stress value exceeds the fracture threshold value, generating prompt information for indicating that the workpiece to be tested has fracture risk.
In this embodiment, the prompt information corresponding to different levels may be generated based on the standard threshold, the yield threshold, and the fracture threshold, for example, when the physical test is performed, the load condition during the physical test may be monitored, when the standard threshold, the yield threshold, and the fracture threshold that the target stress value exceeds are predicted according to the target formula, the corresponding prompt information may be sent to the detection personnel, and at a dangerous moment, for example, when the target stress value exceeds the yield threshold or the fracture threshold, an emergency stop instruction may be sent to control the force application device to stop operating, so as to prevent a test accident from occurring.
In a specific implementation manner, this embodiment may further include the steps of: and generating a detection report according to target data, wherein the target data comprises at least one of a first stress value, a second stress value, a deviation value, a target first stress value, a target second stress value, a target deviation value, an image of the workpiece to be tested and a simulation picture of the simulation workpiece.
Specifically, a report template can be preset, and when a real object test or data prediction is performed, the obtained data is filled into the report template, so that the efficiency of relevant personnel in writing test reports can be greatly improved.
Further, the embodiment may also utilize augmented reality display of the target data.
For example, in the test process, because the test data can change constantly, it may be inconvenient for relevant personnel to view the test result, consequently, can utilize equipment such as VR equipment, AR equipment, show target data through modes such as virtual reality, reality reinforcing to make things convenient for relevant personnel directly perceived to view the test result.
