| 摘 要： | 建立双轴汽车模型对简支梁桥在移动汽车荷载作用下的动力响应问题进行了研究。分别分析了一辆汽车以不同车速、不同车重及通过不同跨径桥梁时的情况,并给出了相应情况下的简支梁桥跨中动位移的变化曲线。对直观地了解车—桥耦合振动系统的动力特性及系统数值模拟具有一定的参考价值。

| Abstract: | In this paper,the dynamic response problem of the beam bridge under the loads of moving vehicles is analyzed by using two-shaft vehicle model.A calculation example is presented,and the maximum dynamic deflection of the beam bridge under the conditions of different speeds,different weights and different lengths of a vehicle is calculated.This study is valuable to the understanding of the dynamic properties and numerical simulation of the bridge-vehicle coupling vibration system. |
