摘要
作者在文献[1]中已求得了弹性点支连续等跨梁的固有频率和固有振型。本文对其在匀速移动载荷作用下的动态响应问题利用模态迭加法进行了求解。另外，关于弹性点支连续等跨梁的振型函数的正交性首次在本文中得到了证明。
Based on the natural frequencies and natural modes of the transverse free vibrations of continuous equispan beams on springs,which have been solved by the writer in [1],thepresent paper deals with the dynamic deflections under moving loads by means of mode superposition method. Moreover,the orthotropic relation to their modes is firstly verified in this paper.
