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

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 braking tests, in particular to a hardware-in-the-loop semi-physical simulation test bed for train braking 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 anti-skid, etc., thereby improving the development efficiency of control methods related to braking control. Before the dynamic control method is applied to the train, a large number of braking tests are also required to ensure its reliability and safety. [0003] Since the line test of train braking requires a lot of hardware support (test trains, test lines, etc.), the line test of train braking requires a lot of resources (funds, personnel, etc.). In addition, in the actual line test, it is necessary to press Test requirements It is very difficult to change the brake test parameters that need to be studied (...
