Energy-absorbing anticreeper of urban railway train

Abstract

The invention belongs to the safety research field of railway traffic vehicles, and particularly relates to an energy-absorbing anticreeper of an urban railway train. The energy-absorbing anticreeper of the urban railway train is composed of an anti-creeping toothed plate, a front baffle, a rear baffle, a foamed aluminum filling pipe, a cylindrical box body wall and a base. In the train collision (face-to-face collision or rear-end collision) accidents, large kinetic energy of the vehicle during the collision is consumed by the ordered large plastic deformation of a box body; and meanwhile, longitudinal collision force is reduced, and retarded velocity is lowered, thus the personnel safety of passengers, drivers and conductors are protected. From the two aspects of the scientific management of impact kinetic energy and the safety protection of passengers, the invention provides a novel energy-adsorbing device. The energy-absorbing anticreeper has the advantages of simple structure, big energy adsorption capacity, stable performances and good protection action on the passengers.

Description

Technical field [0001] The invention belongs to the technical field of passive safety of rail transit, and particularly relates to an energy-absorbing anti-climbing device for urban rail trains. Background technique [0002] Train collision accidents are the main cause of heavy passenger casualties. Therefore, how to improve the safety of train operation and minimize the casualties of drivers and passengers in accidents has become a common concern. Therefore, the passive safety technology of vehicles has become an important technology of vehicle safety design. Passive safety technology uses the energy-absorbing device and the large plastic deformation of the local structure of the car body to orderly absorb the huge energy generated at the moment of impact, thereby effectively protecting the safety of the occupants and minimizing the damage in the event of a vehicle collision. [0003] In the passive safety protection system of the train, the energy absorption device of the lead c...

AI Technical Summary

Problems solved by technology

[0004] The history of rail transit shows that when trains run in the opposite direction or collide with the rear in the same direction, the coupler buffer capacity of the general train is very limited, and it is difficult to absorb the collision energy at a relative speed above 10 km / h, so that the head or head There will be a rigid collision between the tails, which will generate a large transient collision force and damage the structure of the car body. At the same time, the sharp deceleration caused will cause certain damage to the brains of the passengers on the car.
