摘　　要：针对汽车悬架转向系统的特点,提出一种高效便捷的集成设计方法,建立了基于ADAMS/Car与ANSYS的汽车悬架转向系统集成设计平台,实现了有限元分析、刚柔混合多体动力学仿真分析以及性能优化功能。通过对ADAMS/Car、ANSYS及遗传算法模块的二次开发、集成与封装,解决了ADAMS/Car后台调用的难点,实现了刚柔混合多体动力学模型的自动创建。工程设计人员可以脱离ADAMS与ANSYS环境设置悬架转向系统模型参数与仿真参数,快速创建分析模型、执行仿真与结果分析。最后通过对某车型悬架转向系统模型的创建与仿真优化分析,说明了编程过程中关键问题的解决方法,验证了该集成设计平台的易用性与高效性。An efficient and convenient integrated design method is proposed based on the characters of vehicle suspension and steering system.An integrated design platform of vehicle suspension and steering system based on ADAMS/Car and ANSYS is presented and constructed;FEA analysis,rigid-flexible coupling multi-body simulation analysis and optimization are realized.Through carrying out secondary development of ADAMS/Car and ANSYS,background calling of ADAMS/Car and auto-created of rigid-flexible coupling multi-body model is realized.Engineers who are unfamiliar with ADAMS and ANSYS can carry out the modeling,simulation and results analysis after the parameters are set.The simplicity and efficiency of the design platform are verified and the solutions of the key problems through the programming are given by a simple genetic algorithm optimization design example.
