%X 车辆座椅的振动是典型的多维振动。现有一种新型车辆并联减振座椅，能够提供3个自由度的减振形式。对该车辆减振座椅的主体并联机构建立动力学方程，进行了模态分析，确定了座椅系统合理的弹性系数及阻尼系数，然后用MATLAB软件绘制出车辆减振座椅的振动曲线，同时用ADAMS软件进行减振座椅的仿真分析，验证了理论分析的正确性及该车辆座椅有较好的减振性能。<br>The vibration of the vehicle seats is a multidimensional vibration. A new kind of multi-dimensional vibration damping vehicle seat, based on parallel mechanism, can provide a form of three degrees of freedom vibration. Then, the dynamic equation of parallel mechanism of the vibration damping vehicle seat was established, and reasonable elasticity and damping of seating systems were determined by modal analysis. Finally, combined vibration curves of vehicle vibration seat were plotted by MATLAB and the simulation of ADAMS verifies the theoretical analysis result and the vehicle seat has a good damping performance
