为更好地提高某防爆车座椅的平稳性，对比研究了线性被动悬架、天棚控制下的半主动悬架的动力学性能。在建立2种悬架的动力学模型和天棚控制系统的基础上，利用 Adams 与 Matlab/Simulink 联合仿真，获得座椅的库仑阻尼力(FR)时域响应曲线、悬架系统的单位阶跃时域响应曲线、座椅相对于车身的相对位移时域响应曲线。对比结果表明：相对于线性被动悬架系统，天棚控制下的悬架系统在振幅上有了很大的改善，悬架处于稳定状态时被拉伸的长度减小，大大提高了整个悬架的平顺性；同时，整个系统的超调量也减小，调节时间相应地缩短了一些，并增加了整个悬架系统的稳定性。

In order to improve the seat’s stationarity of the anti-explosion car’s cab, the dynamic performance of anti-explosion vehicle traditional linear suspension and semi-active suspension using sky-hook control is studied. On the basis of founding dynamical equation of the two suspensions and founding the system controlled by using sky-hook method, the joint simulation by using Adams and Matlab/Simulink is built. From the simulation, we can gain FR of time domain, the suspension system’s unit step of time domain, seat’s displacement relative to chassis of time domain. The comparisons suggest that semi-active suspension using sky-hook control has some improvement on the amplitude of the vertical direction. The length stretched of the semi-active suspension has some reductions when the semi-active suspension is in a stable state. It improved much comfort of all the suspension’s system. Also the overshoot of the total system gains some decreases. The setting time is also cut down. The stability of the semi-active suspension’s system achieved some improvements.
