Abstract

The invention relates to an end wall structure of a railway vehicle and a processing method of the end wall structure. The end wall structure comprises a front end wall; the front end wall comprises end door stand columns, end corner posts, a door top rail, an end roof camber beam and an end wall plate; the end wall structure also comprises an energy absorption component and a back end framework; the front end wall and the back end framework are fixedly connected with the energy absorption component at two sides of the energy absorption component. The processing method of the end wall structure comprises the steps of a, preassembling the end wall structure; b, fixing the end wall structure to the end of a vehicle body. The energy absorption component and the back end framework are additionally arranged on the end wall structure, the end wall structure can participate in deformation and absorb energy under the impact, the impact resistance performance of the end wall is improved, the safety of the passengers is guaranteed, a modular method is adopted, and the installation efficiency of the end wall structure is guaranteed.

Description

technical field

[0001] The invention relates to an end wall structure of a rail vehicle and a processing method thereof, in particular to an end wall structure capable of deforming and absorbing impact energy when subjected to an impact and a processing method thereof. Background technique

[0002] With the rapid popularization of domestic urban rail transit and the substantial increase in vehicle speed, people have put forward higher requirements for the safety of rail vehicles. At present, the end wall and the car body of rail vehicles are mostly welded structures, and neither the end wall nor the car body is equipped with energy-absorbing components. After a collision, all energy is absorbed by the coupler buffer. The device cannot completely absorb the impact energy, and the remaining energy will cause the vehicle to collide and deform, affecting the safety of passengers.

[0003] A utility model patent with the application number of 200920317585.4 in China discloses an...
