摘要：主要从橡胶节点刚度、油温、安装间隙、倾斜角度等方面对减振器阻尼特性影响进行分析，并基于SIMPACK建立我国某高速列车的动力学模型，仿真分析了橡胶节点刚度对车辆动力学性能影响，分析结果表明：橡胶节点刚度越大，吸收的能量越多，但是节点刚度过大，车辆动力学性能则会有所恶化，故应选取一个最优范围；油温越高，减振器吸收的能量有所下降；由于减振器长期服役带来的安装间隙对阻尼特性影响很大，间隙越大减振性能越差；倾斜角度对减振器吸收的能量几乎没什么影响，对动态特性有一定影响。因此，在减振器试验过程中，应当考虑油温、安装刚度以及安装间隙带来的影响，即减振器要注意散热，反力座刚度要足够大且无安装间隙。

Abstract：The analysis on resistance features of yaw damper is mainly performed from rubber joint points stiffness, oil temperature, installation clearance, angle of inclination in the article. And the dynamic model of one of our country high-speed vehicles is built to analyze the effect of rubber joint point on vehicle dynamic performance based on SIMPACK. It could be concluded that absorption energy would decrease with the increasing of rubber joint points stiffness, but vehicle dynamic performance would be worse when rubber joint points stiffness overranges. Absorption energy of yaw damper would reduce with the augment of oil temperature and installation clearance. Inclination angle of yaw damper makes a small difference on absorption energy, but it has certain effect on dynamic features of yaw damper. Therefore, The consideration shoule be done becaues of the influence of oil temperature, installation stiffness, installation clearance. We are supposed to heat dissipation, enough inclination stiffness and without installation clearance.
Key words：rubber joint point；oil temperature；installation clearance；inclination angle；resistance features vehicle dynamic performance
