摘  要:
针对汽车建模的不精确问题,以汽车的独立悬架作为研究对象,建立其刚性模型和刚柔耦合模型,并在整车环境下通过转向盘角阶跃输入仿真试验来测量横摆角速度、横向加速度和后轮的横向滑移量等参数,分析和对比两种模型对汽车操纵稳定性的影响。结果表明,使用刚柔耦合悬架测得的瞬态值和稳态值较小,汽车的操纵稳定性能更优。

摘  要:
According to the problem that the imprecision of the automobile modeling,taking a vehicle independent suspension as the object of the research,the rigid model and rigid-flexible coupled model are established. The influences of two models of vehicle handling and stability are analyzed and compared with the help of the experiment of the steering-wheel step input simulation. The yaw rate,lateral acceleration and lateral slip of rear wheel are measured. The results show that the transient value and steady- state value are smaller with the rigid- flexible coupled suspension. Naturally,the handling and stability of the vehicle is better.
