STUDY OF VEHICLE-BRIDGE COUPLED VIBRATION USING MATLAB/ SIMULINK

The vibration of a bridge caused by passage of vehicles is one of the most imperative considerations in the design of a bridge as a common sort of transportation structure. In the last few years, Used Simulink for modeling and simulating dynamic systems because it has become the most widely used software package in academia and industry. A major goal of this study is to create a simplified model of a vehicle bridge system in MATLAB and present the basic features of Simulink focusing on modeling of dynamic systems of the bridge vehicle interaction problem. To solve the problem of coupling, the bridge is modeled as Euler Bernoulli beam and the vehicle is considered as 4 D.O.F half car model has been investigated using the Runge-Kutta method applied in Simulink of Matlab. The model will then be used to study the influence of the velocity to vehiclebridge vibrations.
