Firstly, based on the Duhamel integral and dynamic reciprocity theorem, the generalized Duhamel integral expression is written to a point in the half infinity space under moving load. Secondly, the train load is considered as a series of centralized loads with fixed distance. The dynamic response expression of a point in frequency domain and frequencywavenumber domain are derived out through the Floquet transform and Fourier transform under a moving load, and then the dynamic response of a point is gotten ...

以Duhamel积分为基础，首先应用动力互等定理，得到了移动荷载作用下，半无限大弹性连续介质空间上任意点的动力响应的广义Duhamel积分表达式；然后将列车荷载简化考虑为一系列具有一定间距的集中荷载，采用Floquet变换、Fourier变换等方法，得到了一个集中移动荷载作用下任意拾振点ξ的动力响应在频域和频率波数域内的表达式，进而由叠加原理得到列车荷载作用下的动力响应解；最后，通过算例说明该算法的适用性。
