Experiment research of new-type pressure control technology on rapid train's cabin

The new-type pressure control scheme was proposed, which used the idea of cabin pressure control system for airplane. To release the pressure wave caused when two rapid trains travel in tunnel or encounter. The system of simulation test for demonstrating of the scheme was presented. The measurement for resistance characteristic of pressure regulator, static tests when the exterior ambient is in positive and negative pressure and dynamic test when exterior ambient is continuously variable were performed. It has been shown that the scheme is practical.
