Problems solved by technology

[0005] The purpose of the present invention is to provide a hardware-in-the-loop semi-physical simulation test-bed for train braking, to overcome the fact that the research on train braking in the prior art cannot fully consider the complexity and strong non-sensitivity of the brake due to the complete reliance on simulation. Linear problems, or costly problems due to relying entirely on experimentation

Abstract

The invention discloses a train braking hardware-in-the-loop simulation testing stand and method, relating to the technical field of train brake tests. The testing stand comprises a testing-stand virtual part, a testing-stand hardware part and a data collection and signal conversion circuit, wherein the testing-stand virtual part comprises a man-machine interactive interface, a virtual train module for simulating a train and operational environment of the train, and a virtual electric braking module for providing a virtual electric braking force, the testing-stand hardware part comprises a driver controller for generating a train brake instruction and air brakes for providing air brake hardware required by tests, the number of the air brakes matches the marshalling number of a virtual train, and the data collection and signal conversion circuit is used for providing information exchange interfaces of the testing-stand virtual part and the testing-stand hardware part. The testing stand and method take full consideration of the complexity and high non-linearity of brakes, the testing result is accurate, and consumption of tests is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of train brake tests, in particular to a train brake hardware-in-the-loop semi-physical simulation test bench and a test method. Background technique [0002] The test of train braking process can provide test data support for train braking control, especially train braking force control, wheel antiskid, etc., thereby improving the development efficiency of control methods related to braking control. In addition, the newly developed system Before the dynamic control method is being applied to the train, a large number of braking tests need to be carried out to ensure its reliability and safety. [0003] Because the line test of train brake needs a lot of hardware support (test train, test line, etc.), the line test of train brake needs to consume a lot of resources (funds, personnel, etc.). In addition, in the actual line test, according to The test requires that it is very difficult to change the braking t...
