摘要
为了提高作动器减振性能,设计了惯性通道式半主动悬架作动器。建立了力学控制模型,推导出数学模型,求出动刚度、动阻尼和力传递率的表达式。通过改变惯性通道截面积对作动器系统进行动态特性仿真,得到各指标的变化规律。仿真结果表明:所设计的作动器系统减振特性明显,可以为半主动悬架系统提供低频大阻尼力和高频小阻尼力。
In order to enhance the actuator＇s anti-vibration performance,the inertia channel semi-active suspension actuator is designed.The mechanical control model is established,the mathematical model is derived,seeks out the expression of dynamic stiffness、 dynamic damping and force transmission rate.Carries on the dynamic characteristic simulation through the change inertia channel cross-sectional area to the actuator system,obtains various index change rule.The simulation results show that the design of the actuator system anti-vibration characteristic is obvious,may to provide the low frequency big damping force and the high frequency small damping force for the semi-active suspension system.
