    摘要:

    为了研究被动悬架车载主动减振平台的低成本控制策略及其减振效果,针对一种新型长宽比较大的多层减振平台,建立了车辆被动悬架与主动减振平台的一体化全系统动力学分析模型。进而,设计了“线性被动、旋转主动”的平台控制策略,并应用MATLAB及ADAMS软件,在三种典型路面激励下,进行了仿真测试。结果表明:采用垂向线性振动的多层被动减振、旋转振动的低成本主动控制策略,被动悬架车载减振平台的减振效果明显,实现了车载减振平台的高性价比设计。

    Abstract:

    In order to study the low cost control strategy and its damping effect of active vibration damping platform installed in vehicle with passive suspension, an integrated dynamic analysis model of vehicle with passive suspension and active vibration damping platform is established for a new type of multilayer damping platform with big ratio of length to width. Then, a “linear passive and rotational active” platform control strategy was designed, and the responses of vibration damping platform were simulated with MATLAB and ADAMS software under three typical road excitations. The results show that the damping platform installed in vehicle with passive suspension, through the multilayer passive vibration control of vertical linear vibration, low cost active control strategy of rotary vibration, has obvious effect of vibration attenuation, and realizes high the costeffective design of the vehicle vibration damping platform.
