Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
A first embodiment of the present invention provides a wheel and wheel cover prediction method, which is applied to a bench test platform of a vehicle, as shown in fig. 1.
The following describes in detail specific implementation steps of the wheel and wheel cover prediction method provided in this embodiment with reference to fig. 1:
firstly, step S101 is executed to acquire interference test data of the vehicle under a first operating condition of the vehicle, wherein the interference test data is data obtained by testing interference between a wheel and a wheel cover of the vehicle.
Specifically, under a certain working condition of the vehicle, which is referred to as a first working condition, in the process of applying impact force to the wheel, N groups of motion coordinates of the wheel are obtained at preset step intervals, wherein interference test data comprise the N groups of motion coordinates, and N is greater than 1. The magnitude of the impact force applied to the wheels and the preset step length are set according to actual requirements.
Each of the N sets of motion coordinates includes an abscissa value and an ordinate value, wherein the abscissa value is a vertical distance of movement of the wheel in the vertical axis direction, and the ordinate value is a horizontal distance of movement of the wheel in the horizontal axis direction.
The longitudinal coordinate value of each group of motion coordinates is the horizontal distance of the wheel moving in the direction of the transverse axis, and the specific obtaining process is as follows: in the process of applying impact force to the wheels, obtaining the gap distance between one wheel and the wheel cover every other preset step length to obtain a plurality of gap distances; and obtaining a horizontal distance corresponding to each gap distance in the plurality of gap distances according to the plurality of gap distances.
Specifically, under a certain working condition of the vehicle, the bench test platform applies impact force of about 3 times of wheel load in the vertical axis direction (Z axis) to the wheel, so that the wheel moves in the vertical direction (Z axis) and moves in the horizontal direction (X axis). As shown in fig. 2, in the process of applying impact force to the wheel, N sets of motion coordinates of the wheel are obtained every set step length. The abscissa of each of the N sets of motion coordinates is a vertical (Z-direction) displacement of the wheel, i.e., a vertical distance moved by the wheel in the vertical axis direction, and the ordinate is a horizontal (X-direction) displacement of the wheel, i.e., a horizontal distance moved by the wheel in the horizontal axis direction. The connecting lines of the N sets of motion coordinates are solid lines in FIG. 2, and the dotted lines in FIG. 2 are curves of the interference simulation model.
In the specific implementation process, because the horizontal distance of the ordinate value of each group of motion coordinates is directly measured with errors or is inconvenient to directly measure, in order to ensure the accuracy of obtaining the horizontal distance of the ordinate in each group of motion coordinates, the clearance distance between one wheel and the wheel cover is obtained every set step length in the process of applying impact force to the wheel. And under the normal condition, namely when the wheel does not perform horizontal displacement, the fixed distance S between the wheel and the wheel cover is not changed, and a horizontal distance corresponding to a clearance distance, namely a vertical coordinate in each group of motion coordinates, is obtained through the fixed distance S and the clearance distance. Through the specific process of obtaining the longitudinal coordinate value of each group of motion coordinates, the accuracy of obtaining the horizontal distance of the wheel moving in the direction of the transverse axis is improved, and the reliability and the accuracy of the horizontal distance of the wheel moving in the direction of the transverse axis are guaranteed.
Taking fig. 2 as an example, N sets of motion coordinates are set every set step length during the process of applying impact force to the wheel. A first set of motion coordinates (0,0) is obtained before the impact force is applied to the wheel, as in the origin in fig. 2, indicating that the wheel is not moving in the vertical axis direction and not moving in the horizontal axis direction before the impact force is applied to the wheel. After starting, a set step length is set, and the vertical distance of the movement of a wheel in the vertical axis direction is 10 mm, and the clearance distance between the wheel and a wheel cover is 5.5 mm; and when the wheel does not horizontally displace, the fixed distance between the wheel and the wheel cover is 6 mm, and the horizontal distance of the wheel moving in the direction of the transverse shaft is 0.5 mm. Therefore, a second set of motion coordinates (10,0.5) is obtained. Then, a set step length is spaced to obtain the vertical distance of 20 mm for moving a wheel in the vertical axis direction and the clearance distance A mm between the wheel and the wheel cover; and when the wheel does not horizontally displace, the fixed distance between the wheel and the wheel cover is 6 mm, and the horizontal distance of the wheel moving in the direction of the transverse shaft is 6-A mm. By analogy, each subsequent group of motion coordinates can be deduced. Until the motion coordinate when the interference between the wheel and the wheel cover is measured, namely the motion coordinate when the gap distance between the wheel and the wheel cover is zero. Each set of motion coordinates is shown in table 1.
TABLE 1
In the embodiment, the interference condition of the wheel and the wheel cover of the vehicle is simulated through the bench test platform of the vehicle, the motion data, the motion coordinate and the motion track of the wheel in the process from the time when the interference condition never occurs to the time when the interference condition occurs are measured, the authenticity, the reliability and the accuracy of the measured motion data, the measured motion coordinate and the measured motion track are ensured, the precision of the motion data, the measured motion coordinate and the measured motion track is improved, and the precision of the prediction method is also improved along with the precision of the prediction method
Next, step S102 is executed to adjust an interference simulation model of the vehicle based on the interference test data, wherein the interference simulation model is a model simulating the interference between the wheel and the wheel cover.
Specifically, an interference simulation model is constructed through a simulation model, wherein the simulation model includes but is not limited to: the mechanical system dynamics automatically analyzes an ADAMS model and a digital electronic sample vehicle DMU model. And acquiring simulation data through an interference simulation model of the vehicle, wherein the working condition corresponding to the acquired simulation data is consistent with the working condition corresponding to the acquired interference test data. That is, the interference simulation model acquires simulation data under the first condition.
Then, judging whether the simulation data is consistent with the interference test data; if so, taking the interference simulation model as the adjusted interference simulation model; if not, adjusting the interference simulation model through the interference test data.
Taking fig. 2 as an example, the solid line is a connecting line of N sets of motion coordinates, i.e., a curve measured during the interference process between the wheel and the wheel cover, and the dotted line is a curve of the interference simulation model. In fig. 2, the overlapped portion is a portion where the interference test data and the simulation data are identical, and the non-overlapped portion is a portion where the interference test data and the simulation data are not identical. And adjusting and optimizing parameters of the interference simulation model at the non-overlapped part through interference test data to obtain an adjusted interference simulation model. The curve of the adjusted interferometric simulation model is identical to the solid line of fig. 2, and the parameters of each coordinate point on the curve of the adjusted interferometric simulation model are shown in table 2. The adjusted interference simulation model is reliable, and when the wheel is pressed to the limit position in the adjusted interference simulation model, whether the wheel and the wheel cover interfere with each other represents whether the actual wheel and the wheel cover interfere with each other.
TABLE 2
During the application of impact forces to the wheel, there is a limit to obtaining interference test data because actual testing of the wheel is limited. In some extreme or extreme cases, the wheel and the wheel cover may interfere with each other, which, however, cannot be actually tested. The interference simulation model is used for simulating the interference situation between the wheel and the wheel cover, and even after the interference between the wheel and the wheel cover, the situation that the wheel interference exceeds the wheel cover can be simulated, namely, the interference simulation model can simulate the interference situation between the wheel and the wheel cover under some limit or extreme conditions. However, the interferometric simulation model is always a theoretical model, has low reliability and precision, and cannot be directly applied. In this embodiment, the interference simulation model is adjusted by using actually measured interference test data, and the interference simulation model is adjusted by using highly accurate and reliable data, so as to obtain an adjusted simulation model. And the accuracy, precision and reliability of the adjusted simulation model are improved, and the adjusted simulation model can also truly show the interference condition between the wheel and the wheel cover and can be directly used for predicting the interference between the wheel and the wheel cover.
Then, step S103 is executed to predict the interference between the wheel and the wheel cover under the second operating condition of the vehicle by using the adjusted interference simulation model.
Specifically, under other working conditions, even some limit or extreme working conditions, the interference process or the interference condition between the wheel and the wheel cover is predicted through the adjusted interference simulation model with high precision.
Taking fig. 2 as an example, the coordinate point (100, 4.6), at which the clearance distance between the wheel and the wheel cover is 1.4, indicates that no interference occurs between the wheel and the wheel cover. And (4) coordinate points (120, 6) when the clearance distance between the wheel and the wheel cover is 0, indicating that the wheel is in contact with the wheel cover and the interference condition occurs between the wheel and the wheel cover. And (4) coordinate points (150, 7.5) when the clearance distance between the wheel and the wheel cover is-1.5, indicating that the wheel is in contact with the wheel cover and the interference condition occurs between the wheel and the wheel cover.
