The characteristics of pressure reduction are studied experimentally to investigate the behavior of an air brake apparatus which receives a pressure reduction in compressible flow. Improvement of sensitivity and response of the air brake apparatus is required to increase maximum train speed. In order to understand the characteristic of pressure reduction, we devised a test equipment using a new concept and applied it to a few rolling stock apparatuses. It is confirmed that the complicated pressure fluctuation of an actual rolling stock was reproduced to high accuracy by using this characteristic test equipment in a laboratory. As an example, the sensitivity of three types of pneumatic control valves was investigated quantitatively and the characteristic of their sensitivity in emergency braking is discussed. The effectiveness of the equipment is shown through the experiments.
