摘　　要：运用Adams/View建立了某乘用车双横臂扭杆弹簧独立悬架动力学模型,并对悬架运动学特性进行跳动仿真,发现了前轮前束角以及主销内倾角偏大的问题.由于悬架系统结构复杂,优化参数过多,涉及到多目标优化,一般的优化方法很难达到好的优化效果.结合多体动力学软件Adams/View与优化模块Adams/Insight,通过研究悬架部分点坐标对目标函数各悬架定位参数的影响程度,得到设计变量的灵敏度.根据灵敏度合理选择修改设计变量并对这些设计变量进行优化,最终使得目标函数同时达到目标值,车辆运动学性能得到改善.The double wishbone suspension of torsion bar spring of a passenger vehicle was established and operated in Adams/View.Then,it was found out that the toe angle and caster angle is way too large after simulation.Since the complexity of suspension system and excessive number of variables,it would be difficult to take use of familiar ways to reach the ideal result.In this paper,the combination of multi-body dynamics software Adams/View and its optimization module Adams/Insight was introduced.The sensitivity of design variables was received and the parameter values was obtained.Then the object function was reached at the same time with the optimization of several design variables,thus the kinematic performance was improved as well.
