Numerical Simulation of Train-Induced Structural Vibration

Abstract Train-induced structural vibration caused more and attentions nowadays, the present paper developed a numerical approach of train-induced simulation with ANSYS software. The finite element model is composed by buildings, rail, sleepers, ballast several layers soil, moving load represented wheel-rail coupling forces, both solid element, shell beam are used in model. Acceleration time history levels key point on buildings given, effect different forces dynamic response building also numerically investigated. Comparisons free boundary, symmetric fixed boundary transmitting conditions responses illustrated. Numerical results show that, condition type could affect structures near train tracks, validation test should be performed firstly to determine proper amplitude frequency. proposed method provides powerful technic tool for predicting train-induce vibration, employed evaluate control approaches.
