本文提出了一种非比例阻尼系统的结构响应重构方法，该方法是基于经验模态分解法和模态叠加法的时域方法。采用状态空间法对动力系统方程进行解耦，得到复模态振型。详细研究了密集模态下结构系统的响应重构问题。关键的思想是把每一组紧密间隔的模式作为一个整体的一部分。通过两个数值算例验证了该方法的有效性。
An approach of structural response reconstruction for non-proportionally damped systems is proposed in this paper, which is a time domain method based on the empirical mode decomposition method with intermittency criteria and modal superposition method. The state space method is employed for decoupling the dynamic system equation to obtain the complex mode shapes. Response reconstruction of the structural system in the presence of closely spaced modes is studied in detail. The key idea is to regard each set of closely spaced modes as an integral part. Two numerical examples are conducted to validate the effectiveness of the proposed method.
