Accuracy Improvement of Evaluation of Air Brake Wheel Slide Protection by Simulator Test considering Characteristic of Real Hardware

Abstract

The authors developed the Hybrid Simulator (HS) for Wheel Slide Protection (WSP). By using real pneumatic system hardware, the HS improves the reproducibility of the air brake response characteristics which are difficult to model. However, in order to correctly evaluate WSP performance, a test method considering the characteristics of the real pneumatic system hardware is required. In this study, we perform the WSP tests under conditions that suppress the fluctuation of the brake cylinder pressure setting value caused by the tolerance which is inevitably included in real pneumatic system hardware of the HS, and we report the effects of the test conditions on WSP performance evaluation.
