为了提高车辆编组连挂时的平稳性,保证所运货物的完整无损,通过对铁路车辆编组连挂时车钩缓冲装置的冲击特性进行分析,建立编组连挂时的缓冲装置的力学模型,对模型分析解微分方程得出位移时间曲线、加速度时间曲线以及加速度峰值,从而得出编组连挂的最大加速度与车钩系统的阻尼有关。 In order to improve the stability of the vehicle when marshalling, and to ensure that the goods transported intact, by analyzing the impact characteristics of the coupler when the railway vehicle marshalling, the mechanical model of the buffer device when the marshalling is linked, the model Analytical solution of differential equations derived displacement time curve, acceleration time curve and acceleration peak, which concluded that the maximum acceleration of the group linked with the hook system damping.
