摘要
采用无限自由度弹簧质量模型对梁桥在移动车辆荷载作用下的冲击系数问题进行了研究。分析了不同车速、不同跨径情况下移动车辆荷载对简支梁桥动力特性的影响,揭示了梁桥在移动车辆荷载作用下冲击系数的变化规律。
In this paper,the problem of the impact coefficient of an infinite numder degree of freedom spring quality model of the beam bridge at the moving vehicle is presented. The influences of the dynamic behavior of free beam under condition of varied span length and speeds of moving vehicle are studied. This research reveals the change regular patterns of the impact coefficienf of the beam bridge at the moving vehicle loads.
