Universal test bench and test control method for comprehensive performance of railway vehicle brake system

Abstract

The invention discloses a universal test bench and a test control method for comprehensive performance of a railway vehicle brake system. The universal test bench comprises an air compressor, a main blast pipe, a pressure regulating valve, a brake control blast pipe, a brake controller, a control console, a brake pipe, an air control valve, an auxiliary air cylinder, an auxiliary air cylinder pipe, an accelerated release air cylinder, an accelerated release air cylinder pipe, a brake cylinder pipe, a brake cylinder, wheel sets, brake shoes, a brake force sensor, a motor, a coupler, a rail wheel group, a pedestal, an axle box, an axle box pull rod, springs, bearing beams, loading frames, balance weights, linear bearings, loading poles and mounting racks. By establishing the related universal test bench for the comprehensive performance of the railway vehicle brake system, a lot of test researches are carried out for different brake control conditions, so as to master the influences of different brake machines, brake parameters, vehicle axle weights, brake shoe materials and the like to the brake comprehensive performance of trains, thereby providing important test places and reference frames for research and development of railway vehicle brake machines and foundation brake gears.

Description

technical field [0001] The invention relates to a universal performance test bed for the braking system of a railway vehicle and a test control method thereof. Background technique [0002] High-speed, heavy-duty, and urban rail transit are the three directions for the vigorous development of the railway field. Among them, the braking device is the key core component of the railway vehicle. The train can stop running safely, smoothly, and quickly within a specified distance, which is very important for train operation safety. very important. In addition, ensuring the braking capacity under early failure conditions of the braking system, developing the detection technology of the braking system failure state, developing new braking systems and basic braking devices, and avoiding wheel-rail skidding under braking conditions are of great importance for extending the service life of railway vehicles. It is of great significance to improve the service life, improve the innovatio...

AI Technical Summary

Problems solved by technology

The disadvantage is that it cannot reflect the path from the brake cylinder to the brake shoe, and cannot reflect the final braking effect on the wheel set and the dynamic phenomena such as adhesion or sliding between the wheel and the rail during brake shoe braking.

[0006] 2. Only test the braking effect of the brake shoe itself, and the test objects are the brake shoe and the brake disc

Carrying out the braking test on the actual train marshalling on the line can truly and completely reflect the influence of each car, different brake machines and even different braking manipulations, but the test scale is large, the cost of manpower and material resources is expensive, and the line needs to be occupied. Affect normal train operation
