多连杆式悬架运动特性分析与结构参数优化

Analysis of Kinetic Characteristic and Structural Parameter Optimization of Multi-link Suspension

以某汽车五连杆悬架为研究对象,基于ADAMS/Car模块,建立了该结构的多连杆悬架参数化模型,通过仿真研究多连杆悬架结构参数与车轮定位参数、轮距等影响关系,在此基础上,从提高行驶安全性和舒适性出发,利用ADAMS/Insight建立多连杆悬架优化模型,并进行悬架参数优化设计。结果表明,该方法高效可行,可方便地运用于汽车多连杆悬架的设计开发中。

Taking the five-link suspension of a car as the subject investigated on the basis of ADAMS/Car, this paper built the parameterized mode of the multi-link suspension. The simulation shows the influence relations among multi-link suspension structure parameter and the wheel location parameter, wheel track, roll center. On the base of this, aim for improving the ride safety and comfort, multi-link suspension optimization model was built and carried out parameter optimization design by using ADAMS/Insight. The result shows that this method is high-performance and can be used in the design of multi-link suspension conveniently.
