High-speed subway head car body structure

Abstract

The invention provides a high-speed subway head car body structure which comprises an underframe, a car roof, side walls, end walls, a cab framework and a cowcatcher, an underframe end beam is arranged at the end of the underframe, two anti-creeper devices are symmetrically arranged on the outer side of the underframe end beam with respect to the longitudinal center of the car, and the high-speed subway head car body structure is characterized in that a two-stage energy absorption structure is arranged at the end of the underframe; the cab framework is reinforced through design; a one-position end wall framework is arranged behind the cab framework; and a drawer type energy absorption unit is arranged on the cowcatcher. According to the high-speed subway head car body structure, through the arrangement of the two-stage energy absorption structure and the reinforcing design of the cab framework, the collision resistance of the structure is remarkably improved, the passive safety performance meets the requirements of high-speed-grade urban subway vehicles, the collision requirements of trucks on the same line, road vehicles, barriers at the level crossing and the like are met, and a brand-new efficient and safe subway car body structure is provided for subsequent urban subway operation.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle manufacturing, and in particular relates to a high-speed subway head car body structure. Background technique [0002] Most of the existing urban rail transit vehicles are composed of 6 or 8 vehicles, and the design speed level is usually below 100km / h. At the same time, the collision performance meets the C-II level in the requirements of the EN15227 standard, that is, it meets the same formation collision with a collision speed of 25 kilometers per hour. Collision energy is also mostly absorbed by energy-absorbing elements such as couplers or anti-climbers, and the car body structure is less involved in train collision energy absorption. In addition, the collision performance of the car body structure does not consider the working conditions of collision with other freight vehicles or vehicles on the road. [0003] High-speed urban subway vehicles have become favored by many large cities ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that the passive safety performance of existing subway vehicles cannot meet the requirements of high-speed urban subway vehicles, thereby providing a high-speed subway head car body structure that can meet the passive safety performance of high-speed urban subway vehicles. And it can realize mixed operation with other freight vehicles or vehicles on the road to improve urban traffic capacity
