| 摘 要： | 针对简支板梁，建立了移动荷载作用下梁的振动方程和车桥耦合作用下车一梁系统的振动方程，分别解出前者的解析解和数值解，后者采用Newmark算法逐步积分求解。对两种模型下简支板梁跨中的动挠度进行比较分析，结果表明在对简支板梁进行动力分析时，考虑车桥耦合作用是必要的。

| Abstract: | Against to simply supported plate beam,the beam vibration equation under traveling load effect and vibration equation of vehicle beam system under vehicle bridge coupling effect were built,the analytic solution and arithmetic solution of the former were individually solved,while the latter solved with Newmark algorithm step-by-step integration.The dynamic elasticity of simply supported beam of two models were compared and analyzed,the result indicated that it was necessary to consider vehicle bridge couplin... |
