利用积分变换法求解了移动荷载列作用下简支曲线梁桥动力响应的解析解。在讨论过程中将单轴、两轴和四轴三种荷载列模型用一标准荷载列模型来表示 ,使得荷载列模型更具普遍性。在讨论过程中均采用标准函数 ,从而避免了公式推导过程中的不确定因素。最后按本文所给出的计算方法编制了计算简支曲线梁在荷载列作用下的动力响应程序 ,得到了较好的结果
Using the integral transform method, the analytical solution of the dynamic response of simply supported curved beam bridge under moving load is obtained. In the course of the discussion, three kinds of load column models, one-axis, two-axis and four-axis, are represented by a standard load column model, which makes the load column model more universal. In the course of the discussion, standard functions were used, thus avoiding the uncertainties in the process of formula derivation. Finally, according to the calculation method given in this article, a program to calculate the dynamic response of a simply supported curved beam under load is developed, and good results are obtained
