Simulation and Analysis on the Effect of the Stabilizer Bar on the Automobile Steady State Response

运用汽车操纵稳定性能理论分析了横向稳定杆对于汽车稳态响应性能的影响.利用ADAMS/Car仿真软件建立了整车模型,通过改变悬架弹簧刚度实现横向稳定杆的动力学等效,并进行了常半径转向的操作稳定性仿真试验.试验结果表明,通过安装横向稳定杆可以改善汽车的稳态响应,提高汽车的操作稳定性能.

The effect of the stabilizer bar on the automobile steady response is analyzed through the theory of au tomobile steady response. And a model of a whole vehicle is established utilizing ADAMS/Car. Besides, a dynam ical equivalent of the stabilizer bar is built by modifying the spring stiffness of suspension, and a simulation test, which is called constant radius cornering, is executed. The test result shows that the stabilizer bar is able to prove the automobile steady response and improves the automobile handling stability, and that the ADAMS/Car software has the ability to execute accurate simulation test.
