中文摘要:
      车轮在设计完成后,需要进行弯曲和径向疲劳物理试验,检验是否满足疲劳寿命的要求。为解决这种开发模式周期长、成本高的问题,基于弯曲和径向疲劳物理试验的方法,使用Creo和Ansys Workbench软件对材质为A356、规格为16×7 J的某型铝合金车轮,建立三维模型和有限元模型。给出仿真流程和仿真思路,采取静态分析模拟动态分析的方式,预测车轮疲劳寿命和安全系数。仿真结果表明,两种试验仿真中最大应力出现的位置与物理试验的位置相一致,验证了有限元方法预估车轮寿命的有效性,从而可以根据分析结果对车轮进行优化设计。
英文摘要:
      After the design of the wheel, physical testing of bending and radial fatigue is required to verify that the fatigue life is met. In order to solve the problem of long cycle and high cost of this development mode, based on the bending and radial fatigue physical test method, Creo and Ansys Workbench software are used to establish a three-dimensional aluminum alloy wheel model and finite element model. with material A356 and size 16×7 J. In this paper, the simulation process and ideas are given, and the fatigue life and safety factor of wheels are predicted by static analysis and dynamic analysis. The simulation results show that the position of the maximum stress in the two test simulations is consistent with the position of the physical test, which verifies the validity of the finite element method for estimating the wheel life, so that the wheel can be optimized according to the analysis results.
