| 摘 要： | 对移动车辆作用下桥梁的动力反应进行研究，分别采用移动荷载和移动质量两种形式模拟车辆，通过分析桥梁在动力荷载作用下的振动方程及其挠度变化曲线，指出自重及惯性力在桥梁挠度变形中起到的重要作用，比较了两种方法的可靠性及其适用条件。

| Abstract: | This paper presents a study on the dynamic effects of vehicle loads and the response of the bridges through simulations of the vehicle by means of moving load and moving mass respectively. Through an analysis of the vibration equation and deflection curve of the mid - span, it is pointed out that the gravity and inertia load of the bridges plays an important role in the dynamic deflection, and a comparison is made between the two methods in reliability and applicable conditions. |
