The Research On Wheel And Track Vibration And Noise Radiation

City expansion and economics development make the public traffic capacity can't afford so many people. Urban rail transit system offer the way to solve the traffic jam because it is speedy ,on time and it's big capacity. Many city put the Urban rail transit system on the first place. Urban rail transit system run in the crowded district, many people influenced by The vibration and noise subway and light railway. Surface railway make noise disturb people living and meanwhile the subway make vibration will destroy building if it enough harder. How to solve the environment problem bring by Urban rail transit system lead more research focus on it in the world.The wheel-track vibration and noise origin from the different frequencies vibration of components. Some of these vibration spread in air and reflect by structure objects form noise, another action on track structure transfer to ground form Seismic Wave effect on building. Currently some means are used to control...
