摘　　要：侧风作用影响汽车行驶的稳定性,通过侧风描述,基于虚拟仿真技术,利用ADAMS/Car分析运动特性,并且建立LQG主动控制器,研究悬架特性对汽车侧风稳定性的影响,实验发现采用主动油气悬架技术改善汽车侧风稳定性的可行性,为进一步的研究与设计提供了依据。Crosswind effects vehicle stability. Based on virtual simulation technology,describe crasswind and use ADAMS/Car analysis vehicle movement. Then establish LQG active controller,research Vehicle stability under crosswind by suspension performance ,find that active Hydro-pneumatic suspension improve vehicle stability under the crosswind, which provide a basis for further study and design.
