内容简介：
with the rapid development of modern railway paenger and reident bee more concerned about the traininduced vibration and noie along the railway. new technology need to be applied to meaure evaluate and control the vibration and noie. vehicletrack coupling dynamic imulation i uch a proven and practical tool. by coupling the vehicle ytem and track ytem through wheel rail interaction one coupling vehicletrack coupling model can be etablihed and olved.
modern railway alo call for new tructure and technology uch a continuou welded rail high peed turnout lab track etc. thi book can provide ufficient upport to develop new tructure of modern railway.
