| Popis: | 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. |
