A Hybrid Simulator for Wheel Slide Protection Combining Pneumatic Brake Hardware and a Real-time Computer

Abstract

In the performance evaluation of wheel slide protection system, the adjustment of the control algorithm by the on-track test is the most important process. However, it is not easy to stably reproduce the low adhesive condition between the wheels and rails in the on-track test, so the control algorithm must be adjusted under different adhesion conditions for each run. Therefore, in this research, we have developed a hybrid simulator that combines a real-time computer and pneumatic brake hardware. The developed simulator can specify arbitrary adhesion conditions, vehicle models, and control algorithms. This paper introduces its functions and examples of results.
