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。
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.
