双球头型双横臂前悬架系统的开发

摘要

以某轿车平台开发为例,介绍了双球头型双横臂前悬架的布置机理,应用多体系统动力学对悬架性能进行了优化,并与标杆车进行对比分析.结果表明,双球头型双横臂前悬架具有更多的设计自由度和更好的性能优化潜力,通过合理的设计优化,能获得优良的整车操纵稳定性和行驶平顺性.%Taking the development of a car platform as example, the layout mechanism of front double joint double wishbone suspension system is presented. By applying multi-body system dynamics, the performance of suspension is optimized and then benchmarked with three benchmark cars. The results indicate that this type of suspension has more design freedoms and better potential of performance optimization. Through reasonable design optimization, good handling and stability as well as ride comfort of vehicle can be achieved.
