碩士 === 國立臺灣科技大學 === 機械工程研究所 === 83 === This thesis studied the random responses of vehicles travelling on a bridge with irregular surface modelled by a flexible beam with nonlinear behavior .The vehicle is simplified as a 4-DOF system with two point input from ground . The vehicle suspension and damping characteristics are idealized to be linear. The bridge is a finite length , uniform section simply supported beam .In the process ,the equations of motion are decoupled in terms of generalized coordinates .Accordingly , the state-space approach and the iterative equivalent linearization technique are applied for solving the problems . The influence of vehicle velocity and surface irregularity on the system responses is investigated by using numerical examples.
