富氏级数法解无限长链式周期结构的动力响应

Finding the Dynamic Response of Infinite Periodic Chain Structures by Fourier Series

借助富里埃级数理论,讨论了具有无限个子结构的链式周期结构的动力分析问题,对具有周期性约束条件的自伴微分方程的解答,给出了按本征函数展开的表达式。

Using the theory of Fourier series, we discuss the dynamic analysis of periodic chain structures with infinite substructure. Thus, we are able to give the eigenfunction expansion of the solution to self-adjoint differential equation with periodic constraint.
