摘要
快速货运动车组安装的是密接式车钩缓冲装置,车钩间隙的大小对列车的纵向冲击有较大的影响。通过分析快速货运动车组车钩缓冲装置结构、相关参数和车钩力的产生机制,建立快速货运动车组动力学模型,对动车组在启动和制动工况下不同车钩间隙对车钩力的影响进行了分析。
Express freight EMUs are installed with tight lock coupler draft gears, the size of the coupler clearance dramatically affects the longitudinal impulse of the train. Kinetic model of express freight EMU is established by means of analyzing the structure of the coupler gear draft, relevant parameters and the generation mechanism of tractive force of couplers, which enable us to analyze the influence of different coupler clearances on the tractive force of couplers under the conditions of starting, braking and double-headed operations.
