摘要
系统地描述了利用模态分析和有限元分析相结合来识别极坐标各向异性圆板动刚度的方法。该方法取决于：（１）正确的有限元模型；（２）可靠的实验模态分析数据和正确的相关准则；（３）快速又稳健的估算方法。
The main objective of this paper is to investigate a new measurement method to identify plate rigidities of a circular orthotropic disk using vibration data. The method consists of three parts: (1) a correct finite element model; (2) a set of reliable experimental data; (3) a fast and robust estimation method.
