循环双周期系统控制方程的解耦

Uncoupling of Governing Equations for Cyclic Bi-periodic Structures

证明了Ｕ变换方法可使具有循环双周期特性的运动方程组（代数或微分方程组）解耦，给出了解耦方程的基本形式，所得结果可广泛应用于循环双周期系统的静力与动力分析．

The advantage of applying the U-transformation method is to make it possible for the linear simultaneous equations, either algebraic or differential equations, with cyclic bi-penodicity properties to uncouple. This paper provides a rigorous proof for this significant statement and gives the form of the uncoupled equations. The result can be easily used in the procedure to obtain the solutions for static and dynamic analyses of bi-periodic structures.
