轿车转向轮高速摆振研究

Study on Steering Wheel Shimmy of Car at High Velocity

以多体系统动力学理论为基础 ,应用ADAMS软件建立轿车麦弗逊式前悬架多体系统模型 ,并对悬架性能进行仿真计算。在大量的道路试验和仿真计算的基础上 ,提出在工程上可行的克服该车转向轮高速摆振的方法。

In this paper, based on the multibody system dynamics, a 1/4-suspension model with 27 DOFs for the car′s front MacPherson suspension was built by using the ADAMS software A series of digital simulation are performed Then a method to control the steering wheel shimmy of car at high velocity has been put forward A series of road tests have been carried out, which prove that the method is effective
