Pressure transients induced by a high-speed train passing through a station

摘要

The current work experimentally investigates the pressure transients induced by a high-speed train passing through a station as well as two trains passing by each other at stations. The experiments were performed by using 1/20th scale train models with a head car and an end car on a moving model rig at different speeds. Pressure transients were measured using pressure sensors on platform screen doors and car body surfaces. The characteristics of pressure transients on the car body surface and platform screen doors when a single train passes through stations and two trains pass by each other at stations are discussed. The influence of the laws of train speed, crossing position and other parameters on the pressure change of the platform screen doors and on board is analysed. (C) 2014 Elsevier Ltd.
