导向机构对悬架定位参数影响的仿真分析

Simulation Analysis of Orientation Machine on Influence of Alignment

为了进一步提高汽车的舒适性和操纵稳定性,目前在中高级轿车中普遍采用双横臂和多连杆独立悬架,两者的不同主要是其导向机构的差异。导向机构的不同必然导致悬架整体性能的差异,本文从该角度入手通过运用多刚体动力学软件ADAMS建立了两种悬架的模型,分别进行了轮跳试验的仿真分析,比较研究了两种导向机构对决定悬架性能优劣的车轮定位参数的影响,为悬架的设计和开发提供了一定的参考依据。

In order to improve the vehicle ride performance and handling performance, recently double-wishbone and multi-link suspension have been adopted to intermediate and advanced vehicles universally. Both have a difference in orientation machine which can cause the difference in the whole suspension performance. From this angle, two types of suspension models were set by ADAMS and wheel travel simulation analysis was done. The influence of alignment parameter by different orientation machine was researched comparatively and the results will provide reference for suspension design.
