| 摘 要： | 以一自由度半主动悬架模型为研究对象,通过调节模型中的阻尼来实现悬架刚度和阻尼的同时可调。建立5种不同的开关阻尼控制形式及被动悬架模型,分别以正弦输入和白噪声输入作为路面输入激励,在MATLAB中建模并仿真。从幅频响应和时频响应两个方面分析仿真结果,得出开关阻尼控制方法能有效的改善车辆平顺性的理论依据。

| Abstract: | This paper mainly researches a one degree-of-freedom semi-active suspension system.The stiffness and damping of this model can be shifted through altering the damping.Five different types of on-off control systems are built up and simulated in MATLAB with sinusoidal base excitation and white noise excitation.At last,through analyzing the simulations results from frequency responses and time responses,the on-off control system can improve vehicle riding stability effectively. |
