Dynamic Characteristics of Bridge under Moving Constant Load

Abstract:

It is very important to carry out research of dynamic performance and acquire data of bridge. it can provide reference for design of bridge. Combined with a bridge in actual engineering, this paper analyzes the deformation of bridge subjected to vehicles with different velocities. Based on typical theory on vibration analysis between bridge and vehicles and simplified model, finite element model of simple-supported bridge is established by ANSYS software, and concrete process of modeling, solving, analyzing and dealing is introduced. Through the numerical simulation analysis dynamic response characteristics of the bridge body are acquired when the vehicle passes through the bridge at different speeds, variable regularity is given for dynamic response and these can provide good reference for controlling the vibration measures of bridge under moving loads.
