摘要
利用“惯容-弹簧-质量”系统的反共振,提出一种理想天棚阻尼的被动实现方法,设计了被动天棚阻尼悬架系统,建立悬架系统的整车模型,对比分析了传统被动、理想天棚及被动天棚阻尼悬架系统性能。结果表明,与传统被动悬架相比,被动天棚阻尼悬架能够抑制车身在1~3Hz的垂直、俯仰和侧倾振动,车身垂直、俯仰和侧倾加速度均方根值,分别减小了14%、14.6%和9.3%,被动天棚阻尼悬架能够提高车辆的乘坐舒适性,实现理想天棚阻尼悬架的主要功能,研究结果从理论上验证了理想天棚阻尼被动实现方法的正确性与有效性。
Based on inerter-spring - damper structural system, a passive realization method of ideal skyhook-damping was presented by using the anti-resonance of the inerter - spring - mass system. A passive skyhook-damping suspension system was designed. The whole car model of the suspension was built to compare the performance of conventional passive, ideal skyhook-damping and passive skyhook- damping suspensions. The results showed that in contrast to conventional suspension, passive skyhook- damping suspension could suppress vertical, pitch and roll vibration of vehicle body with frequency of 1 - 3 Hz. The RMS values of vertical, pitch and roll acceleration reduced by 14% , 14.6% and 9.3% , respectively. The proposed suspension could improve ride comfort and achieve the main functions of ideal skyhook-damping suspension. The results also indicated that the passive realization method of ideal skyhook damping was corrective and effective.
