Development, Based On The The Ansys Car Wheels Performance Test Analysis Program

Wheel is an important component in the vehicle system. The mechanic performance of wheel directly determines the security of vehicle. CAE technique has become to an important implement in the research & development of mechanical productions. Using finite element analysis to analyze the mechanic properties of wheel, the wheel suppliers can optimize the design of wheel, secure the strength, reduce the number of test and design time, and convince the vehicle manufacturers and consumers.Taking vehicle wheel as the research object, this paper integrates ANSYS Parametric Design Language and MATLAB Graphical User Interface to develop a professional program which takes the finite element analysis of the wheel's cornering fatigue test and impact test using man-machine conversation model.This paper proposes the programming of both command flows of wheel finite element analysis using APDL under the wheel's cornering fatigue test and impact test criterions. The program includes preceding management, solution, getting the element's stress and strain, and post management.This paper develops the professional program which can automatically output the relevant ANSYS command documents of different wheels under MATLAB GUIDE programming environment. By this program, user needs only to input the changed testing parameters in the man-machine conversation interface to get the ANSYS input-file which can order ANSYS to do analysis automatically.In the end, the finite analysis of one wheel's cornering fatigue test was taken by this program. This paper discusses the fatigue theory and prognosticates if the wheels would pass the test. In the mean time, the impact test finite analysis was taken and the conclusion was analyzed by the company's criterion to prognosticate real impact test. The real tests were taken to validate both results of the two finite element analysises.
