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...
