Abstract

The embodiment of the invention provides a rail transit vehicle traction/brake test bench and method. The test bench comprises a front fixing base, a rear fixing base, an idler wheel platform, synchronous gear boxes, accompany type transmission systems, accompany type motors, a controller and a power source, wherein the idler wheel platform is provided with accompany type wheels corresponding to wheels of a vehicle controlled by a rail transit vehicle traction/brake control system one by one; the synchronous gear boxes correspond to and are connected with the accompany type wheels one by one; the accompany type transmission systems correspond to and are connected with the synchronous gear boxes one by one; the accompany type motors correspond to and are connected with the accompany type transmission systems one by one; the controller is connected with the accompany type motors. When the rail transit vehicle traction/brake test is conducted, a rail transit vehicle only needs to be put on the rail transit vehicle traction/brake test bench, the rail transit vehicle traction/brake test can be conducted, the actual rail is not occupied, the test can be conducted at any time according to the requirements, the test cycle is shortened, the manpower and material resources required by the test are reduced, and operation of the actual line is not affected.

Description

Technical field [0001] The invention relates to the technical field of testing, and more specifically, to a rail transit vehicle traction / brake test bench and test method. Background technique [0002] As my country's railway operating mileage increases and train operating speed continues to increase, the requirements for train traction / braking performance are becoming stricter. Traction / braking performance test is an important part of rail transit vehicle performance test. [0003] At present, the traction / braking performance test of rail transit vehicles can only be performed on actual rails. In order not to affect the normal train operation, the test needs to be conducted at a specific time. Therefore, the current traction / braking performance test of rail transit vehicles The braking performance test method has a long test period and requires a lot of manpower and material resources. Summary of the invention [0004] The purpose of the present invention is to provide a rail tra...
