| Abstract: | Based on Euler-Bernoulli beam theory,the model of vehicle-bridge coupled vibration system is established through the simulation of the irregularity of bridge surface by adopting sine function,and the differential equations with non-autonomous variable coefficient which is corresponding to practical conditions is established,hence changes the current model of vehicle-bridge coupled vibration system and has practical significance for the exploration of bridge design and the mechanism of vehicle-bridge coupled... |
