Abstract: This article discusses the common control methods of semi-active suspension, establishs mathematical models of passive suspension and semi-active suspension of automobiles, and establishs ADAMS and MATLAB co-simulation models for passive suspension, skyhook damping control switch-type semi-active suspension and optimal control semi-active suspension based on the mathematical models. Through a comprehensive analysis of the body vertical acceleration, suspension dynamic deflection and tire dynamic load, it is concluded that compared with passive suspension, the skyhook damping control switch-type semi-active suspension and the optimal control semi-active suspension significantly improve the ride of the vehicle and maneuvering stability.

Key words: Sky-hook damping control; Optimal control; Semi-active suspension; ADAMS and MATLAB co-simulation

摘要： 文章探讨了半主动悬架常见的控制方式，建立了汽车被动悬架和半主动悬架的数学模 型，并根据数学模型分别建立了被动悬架、天棚阻尼控制开关式半主动悬架和最优控制半主 动悬架的 ADAMS 与 MATLAB 联合仿真模型。通过对车身垂直加速度、悬架动挠度和轮胎动 载荷的综合分析表明，相比于被动悬架，天棚阻尼控制开关式半主动悬架和最优控制半主动 悬架显著提高了汽车平顺性和操纵稳定性。
