摘要
文中对汽车半主动悬架系统的仿真分析采用了ADAMS和MATLAB联合仿真方法。在ADAMS中建立了1/4汽车悬架的动力学模型,然后用MATLAB软件建立汽车半主动悬架的阻尼控制模型,通过改变阻尼系数减小汽车的垂直振动。在MATLAB/SIMULINK中建立采用模糊逻辑控制的控制系统模型,分析汽车车身垂直方向的加速度,来达到汽车行驶的平顺性。ADAMS和MATLAB联合仿真方法为汽车动力学仿真提供了一种新途径。
The simulative analysis of automotive semi-active suspension frame system adopted the ADAMS and MATLAB joint simulation method. The dynamics model of 1/4 automobile suspen- sion frame was established in the ADAMS, and then using MAT- LAB software to establish the damping control model of automobile semi-active suspension frame, and reduced the vertical vibration of car by means of changing the damping coefficients. Within the MATLAB/SIMULINK to establish control system model by adopting the fuzzy logic control, to analyze the acceleration in the vertical di- rection of car body so as to reach the running easement of automobile. The joint simulation method of ADAMS and MATLAB provided a new way for the dynamic simulation of automobile.
