虚拟台架在汽车底盘零部件优化设计中的应用

Application of Virtual Test Bench in Optimization Design of Parts of Automotive Chassis

以某车型板簧减震器支架疲劳试验为例,利用Solidworks软件建立疲劳台架试验辅助设计平台进行虚拟试验台架设计,并完成台架试验,通过对零部件失效部位进行分析,确定失效模式,通过台架试验和虚拟台架仿真反复相互校核的对比方式,得到零部件最终的优化设计方案。文章通过上述实例来探讨虚拟台架仿真在汽车底盘零部件疲劳试验和优化设计中的重要作用,从而形成一个闭环的汽车底盘零部件的开发流程,有助于提高汽车底盘零部件开发的效率。

The paper takes plate spring damper bracket fatigue test of a vehicle type as an example. The virtual test bench was designed by fatigue bench test aided design platform which built by Solidworks. And then accomplish the bench test. The failure mode is determined by analyzing the failure position of the chassis parts. The bench test and simulation of virtual test bench can be checked each other through the comparison of themselves. Then the fmal optimized design scheme of the chassis parts can be confirmed. In this paper, the important effect of simulation of virtual test bench for the bench test and optimization design of chassis parts will be discussed through the example stated above. Then a closed loop of the develop -ment process for automobile chassis parts can be built. It will help to improve the efficiency of automobile chassis parts development.
