目前国内外高速列车中对于车间纵向减振器的应用较少。为了解车间纵向减振器对列车动力学性能的影响，根据CRH380B型动车组实际参数，运用动力学仿真软件SIMPACK建立装有车间纵向减振器的四动四拖八节编组列车系统动力学模型。通过改变车间纵向减振器的阻尼与节点刚度来分析其对列车平稳性、稳定性和曲线通过性的影响。分析结果表明：车间纵向减振器特性参数对车体横向加速度、车体摇头运动、横向平稳性指标等车体的横向动力学性能有一定影响，其中对车体1~3 Hz的低频摇头运动有明显的抑制作用，抑制效果达到了36.4%；但是车间纵向减振器特性参数对列车走行部的动力学性能影响相对较小。安装合理阻尼与节点刚度的车间纵向减振器能够有效地提升列车整体动力学性能。

Nowadays, there are few applications of longitudinal dampers in the high speed EMUs all over the world. In order to research the influence of the inter-vehicle longitudinal damper on dynamic performance of the high speed EMUs, the dynamic simulation software SIMPACK is used to establish a train dynamic model with inter-vehicle longitudinal dampers of four motors and four trailers based on the actual parameters of CRH380B high speed EMUs. Analyze the influence of the inter-vehicle longitudinal damper on riding quality, stability and curve performance by changing the damping and joint stiffness of damper, result shows as:the inter-vehicle longitudinal damper characteristic parameters have certain impact on the lateral dynamic performance of the vehicle body, such as the lateral acceleration, riding index and the low-frequency yaw during 1-3 Hz which obvious restrained by 36.4%; however, the impact on the dynamic performance of the bogie and wheelsets are relatively small. In summary, installing the inter-vehicle longitudinal damper with reasonable damping and joint stiffness can effectively improve the overall dynamic performance of the train.
