Pull-type high-speed train crash test bench

Abstract

The invention provides a pull-type high-speed train crash test bench, and belongs to the field of railway vehicle crash test. The pull-type high-speed train crash test bench comprises a rigid wall anda crash vehicle body, wherein the rigid wall is arranged at the front end of a rail. Four vertical columns are arranged on two sides of the rail, front beams and rear beams are arranged at the top ends of the vertical columns on the two sides of the rail, I-shaped steel guide rails are erected in the middles of the front beams and the rear beams, a front limiter and a rear limiter are arranged attwo ends of the guide rail, a tensioning wheel is arranged on the middle upper portion of the guide rail, the front beams are provided with driven wheels, the rear beams are provided with pulling mechanisms, an output shaft of a pulling motor is connected with a speed changer, the speed changer is connected with driving wheels, one end of a pulling steel rope is fixed to the front end of a pulling trolley, the other end of the pulling steel rope bypasses the driving wheels, the tensioning wheel and the driven wheels and is fixed to the rear end of the pulling trolley, electromagnets are arranged at the bottom of the pulling trolley, a high-speed photographic system measuring head is arranged at the top of the rigid wall, a speed sensor is positioned on the right of the rail, four speed measuring heads are parallel to the rail, the rigid wall is provided with a force sensor, and electromagnet holders are arranged at the top of the crash vehicle body.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle collision test. Background technique [0002] The collision accident of rolling stock is one of the most serious accidents in the safe operation of rolling stock. However, once a high-speed train collides, it will cause irreparable losses and cause great damage to the life and property of passengers. All countries are focusing on the passive safety protection of rolling stock, and the crash test bench has become an important means and an indispensable part of the test for the passive safety protection technology of rolling stock. Chinese patent application number CN 102501875 A proposes "a step-by-step Multi-stage gas compression energy-absorbing locomotive and vehicle anti-collision "through three-stage cylinders and pistons extruding gas to absorb energy, used for energy-absorbing research of structural components, not used for vehicle body ejection collision, Chinese patent application num...
