Method for Shortening Idle Running Time Using Body Suspension Air Spring Pressure

Abstract

As one of the measures to quickly stop high speed vehicle in the emergent event such as an earthquake, we have devised a method of reducing brake idle running time by supplying the vehicle body suspension air spring pressure preferentially to the brake cylinder pressure. This paper reports on tests to verify this method aimed at shortening idle running time in braking, carried out with Shinkansen bogies placed on a test plant and shows the result of numerical simulations using data from trains in revenue service.
