High Speed Railway Track Dynamics

Xiaoyan Lei is professor and director of Ministry of Education (MOE) Engineering Research Center of Railway Environmental Vibration and Noise, East China Jiaotong University, Nanchang, China. Prof. Lei was the president of East China Jiaotong University during 2007-2016. He received his M.E. degree from Shanghai Institute of Railway (now Tongji University) in 1984 and Ph.D. degree from Tsinghua University, Beijing in 1989. His research focuses on high-speed railway track dynamics, vibration and noise of rail transit environment, and the theory, test and design of high-speed railway track structure.
