摘要
为解决理想天棚阻尼要求阻尼元件与惯性参考系相连的技术问题,利用"惯容-弹簧-质量"系统的反共振现象,提出一种理想天棚阻尼的被动实现方法.将这种方法应用于车辆悬架,建立悬架的半车模型,分析悬架系统的频响特性,从理论上检验理想天棚阻尼被动实现方法的正确性与有效性.结果表明,被动天棚阻尼悬架改善了车辆的低频频响特性,有效抑制了车身垂直和俯仰振动,提高了车辆的乘坐舒适性,实现了理想天棚阻尼悬架的主要功能.
A passive realization method was presented for ideal skyhook damping to solve the technical problem in connecting the damper with the inertial reference system. This method takes the anti resonance phenomenon in the inerter-spring-mass system. The passive realization method of ideal skyhook damping was applied to the vehicle suspension. A half-car model of passive skyhook-damping suspension was built to analyze the frequency-response characteristics of the suspension. The correctness and validity of the passive realization method of ideal skyhook damping were verified in theory. The results show that passive skyhook-damping suspension improves low-frequency response characteristics of vehicle. It inhibits the body＇s vertical and pitch vibration, as a result, improves ride comfort, and shows the main functions of the ideal skyhook-damping suspension.
