| 摘 要： | 用积分变换法求解了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 ,使得荷载模型更具有普遍性 .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

| Abstract: | In this paper the integral transform method is used to analyze the dynamic response of simply supported curved-girder under moving load series,and gets the closed-form soulions to the dynamic response.A standar d load series model was defined to represent single-axis,double-axes and foura xes load series models.With the standard load model,dynamical responses of simpl y supported curved beam were determined.Since no self-defined functions were ut ilized,the deduction process is unequivocal and results in a reliable result.Acc or ding to these we have completed the program which can calculate the dynamic resp onse of curved-beam under moving loads. |
