Coupler Draft Gear of intercity EMU and Collosion Energy Absorption Configuration

摘要:

本文介绍了城际动车组车钩缓冲装置的特点,并分别对前端全自动车钩缓冲装置、中间半永久车钩缓冲装置的主要结构型式、主要参数、作用原理,以及车钩的吸能能力等进行了详细说明。通过建立一维多体动力学模型,对列车分别以5km/h、15km/h、25km/h速度进行撞击时各车钩缓冲装置的车钩力等关键参数进行了分析计算,结果满足设计要求。

Abstract:

This paper introduces the characteristics of intercity EMU concept, and separately to the automatic couplers, semipermanent coupler main structure, main parameters, and the energy absorption ability of the coupler are described. Based on the one-dimensional dynamic model, the coupler force and other key parameters of each coupler buffer device were analyzed and calculated when the train impacted at 5 km/h, 15 km/h and 25 km/h respectively. The results meet the design requirements.
