In this paper, a new procedure is developed to decouple the governing equations of non-classically damped structures with frequency dependent properties. To start, a modal state formulation is used to eliminate the off-diagonal elements that damping might otherwise create in the transfer matrix. From there on, the transfer matrix is expanded in series and decoupling is achieved through an iterative scheme, which relies on the successive inversions of a diagonal matrix only. This approach is finally shown to converge fast and to perform well on the hydroelastic responses of a floating bridge.

具有频率相关特性的结构的新解耦策略

在本文中,开发了一种新程序来解耦具有频率相关特性的非经典阻尼结构的控制方程。首先,模态状态公式用于消除阻尼可能在传递矩阵中产生的非对角线元素。从那时起,传输矩阵被串联扩展,并通过迭代方案实现解耦,该方案仅依赖于对角矩阵的连续求逆。这种方法最终证明可以快速收敛并且在浮桥的水弹性响应上表现良好。
