Dynamic Simulation of a Brake Valve in Air Brake System 2009-28-0030

In the product development cycle, the study on the dynamic behavior of the product helps to freeze the concepts and physical level design rapidly. The lumped parameter approach and bond graph technique makes the dynamic simulation a handy tool for studying the product behavior.
In air brake system, the response time for brake application and release is critical for vehicle stopping distance and obtaining appropriate driver feel. In this paper, an attempt has been made to simulate the dynamic response of the brake valve. One of the commercial software which has standard libraries for pneumatic components, employing bond graph technique and lumped system has been used for developing physical-based modeling and to perform the simulation. The model is simulated for the actual test conditions. The simulated results are compared with experimental results.
