车辆操纵稳定性及平顺性的协同优化研究

摘要

利用车辆多体动力学模型与多目标优化工具,对悬架弹簧、减振器及横向稳定杆特性进行操纵稳定性与行驶平顺性的协同优化仿真.结果表明汽车的操稳性和行驶平顺性的各项性能指标均得到了改善.%By using multi-body dynamics model and multi-objective optimization tools, a cooperative opti-mization simulation for controllability/stability and ride comfort is conducted on suspension spring, shock absorber and anti-roll bar of a car. The results show that all performance indicators in controllability/stability and ride comfort of the car are concurrently improved.
