Analysis of the howling of metro vehicle sliding plug door and the optimization
With the rapid development of urban rail transit and constant increase of operation speed of metro trains,higher requirements on the airtightness and riding comfort of the vehicles have been put forward.In order to solve the problem of air leakage and howling of the sliding plug doors when running at high-speed in tunnels,this paper analyzes the reasons from the perspective of pressure fluctuation in metro vehicles,door condition,door leaf strength,etc.,and proposes optimization measures and solutions in combination with mechanical adjustment,all these measures have been verified in actual metro operation,which provides a reference solution to the problem of air leakage and howling from the sliding plug door system during high-speed operation in tunnels,and is of widely promotional value.
