Modal Analysis and Time Series Model for Synthetic Damped System

本文定义同时计及粘性阻尼和结构阻尼的系统为综合阻尼系统。讨论了多自由度比例综合阻尼系统的模态分析。推导出传递函数矩阵的表达式。应用拉氏变换和Z变换间关系,得到系统的ARMA时间序列模型。

In the present paper, the damped system which takes into account both viscous damping and structural damping is defined as the synthetic damped system. The modal analysis of themulti-degree-of-freedom proportional synthetic damped system is discussed. The representation for the transfer function matrix is derived. By the relationship of Laplace transform and Z-transform, the ARMA time series model for this system is obtained.
