A traction type high-speed train crash test bench and its test method

Abstract

The invention provides a traction-type high-speed train collision test bench, which belongs to the field of rail vehicle collision tests. It includes a rigid wall and a collision car body arranged at the front end of the track; The crossbeam and the rear crossbeam, the middle part of the front and rear crossbeams is erected with I-shaped steel guide rails, the two ends of the guide rails are respectively equipped with front stoppers and rear stoppers, the upper part of the guide rails is equipped with a tensioning wheel, and the front beam is provided with driven wheels; The rear beam is equipped with a traction mechanism, the output shaft of the traction motor is connected with the transmission, and the transmission is connected with the driving wheel; one end of the traction cable is fixed with the front end of the traction trolley, and the other end bypasses the driving wheel, the tensioning wheel and the driven wheel, and connects with the traction trolley. The rear end of the traction trolley is fixed, the bottom of the traction trolley is equipped with an electromagnet, the top of the rigid wall is equipped with a high-speed camera system measuring head, the speed sensor is located on the right side of the track, four speed measuring heads are arranged parallel to the track, and the rigid wall is equipped with a force sensor; The top of the collision car body is provided with an electromagnet suction seat.

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...
