摘要
在文献［１］已求得自由振动解的基础上，本文首先采用模态迭加法，求得弹性地基上四边自由正交各向异性矩形中厚板的受迫振动解，然后应用到我国目前常用的轨枕板上，求得其在列车通过时的动力响应解。
Based on the free vibration of the rectangular mid thick orthotropic plate with free edges on Winkler foundation and the natural frequency and modes of concrete slab sleeper,which have been solved by the writer in ,first,the ordinary solution to the forced vibration of the plate is worked out by means of mode superposition method.Then,the corresponding result is applied to the concrete sleepers being used in China,the dynamic responses of which loaded by passing train are solved.
