以改善车辆乘坐舒适性为目的，通过分析车体垂向速度和垂向加速度的相互关系，设计了车辆悬架改进型天棚阻尼半主动控制算法。以天棚阻尼控制算法为对比，对设计的算法进行性能仿真。结果表明，与传统的天棚阻尼控制算法相比，该算法能显著降低车体加速度，提高乘坐舒适性，且具有计算量小，简单实用的优点，适用于车辆振动的控制。

Aiming at improving vehicle ride comfort and by analyzing the mutual effects between vertical ve-locity and vertical acceleration of vehicle, a modified sky-hook damping semi-active control algorithm for vehicle suspensions is designed. With conventional sky-hook damping control algorithm as comparison reference, a suspen-sion performance simulation is conducted with the algorithm designed. The results show that compared with conven-tional sky-hook control algorithm, the modified sky-hook control algorithm can significantly reduce the acceleration and improve the ride comfort of vehicle with the merits of being simple, practical with less computation efforts, suit-able for vehicle vibration control.
