Problems solved by technology

The existing test traction and braking systems, because they do not carry out mutual cooperation tests, require a lot of time to adjust the relationship between electric braking and air braking after the products of both parties are installed, until they achieve mutual cooperation and smooth transition

Abstract

The invention provides a traction brake test system used for testing traction systems and / or braking systems of rail transit vehicles. The traction brake test system comprises a test table, a measurement and control unit and a semi-physical simulation platform, wherein the test table is used for simulating vehicle transmission systems and vehicle load inertia and comprises a motor speed change unit, a flywheel inertia simulation unit and an axle unit used for simulating the axle of a tested vehicle which are sequentially connected with one another; the measurement and control unit comprises a driver controller, a traction control unit, a traction current converter, an electrodynamic braking control unit and a braking control unit, a first signal simulation platform for simulating a brake signal, and a second signal simulation platform for simulating a traction signal. According to the test system, the traction system and the braking system are integrated for testing, axle loads of multiple specifications of motor cars and urban rails can be realized, an interactive test of the traction system and the braking system under the uniaxial condition is simulated, the testing efficiency is improved, the research and development cycle of novel products is shortened, and the loading trial time is shortened.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a traction braking test system for rail transit vehicles. Background technique [0002] Rail transit vehicles, such as bullet trains and urban rail vehicles, have two independent braking systems, namely electric braking (ED braking) and electropneumatic braking (EP braking). In the case of common braking, the electric brake without wear is preferred; when the speed is below a certain set value (such as 10km / h) in the low speed range, the air brake is used to replace the electric brake (hybrid brake) to Ensure that the impact is small when switching from electric braking to air braking; for emergency braking, air braking is used on each axis, and electric braking is additionally applied to the power shaft. [0003] The electric brake is provided by the traction system, and the air brake is provided by the brake system. During the product development process of the rail vehicle tr...
