摘　　要：以某轿车的前悬为例,基于多体动力学理论,利用拉格朗日乘子法,采用虚拟样机技术,借助MSCAdams/car软件,建立某轿车前悬的多体动力学仿真模型,深入地分析前轮定位参数随车轮跳动的变化关系.结果和实测值、理论值相一致,表明该分析方法对产品的优化设计、缩短产品的研制周期具有重要的实际意义.The front suspension of a car is taken as an example, according to the multi-body kinematics theory, making use of Lagrangian method, applying Virtual Prototyping Technology and software Adams/car, the front suspension math-model of a car is built, and deep simulation analysis for its alignment parameters is carried out. The result is consistent to the real experiment and the theoretical analysis. So this method is practicable to the optimizing design of manufacture and shortening its study periods.
