摘　　要：大型复杂工程结构经常要求进行动力学设计。针对某复合材料平面板架结构,分别采用随机激励的模态参数识别法和相位共振的纯模态法,进行实验模态分析,给出各阶模态参数值。试验表明,纯模态方法可以给出较高精度的模态参数。The dynamics design is usually required for modem large complicated structure. In this paper, a pure modal test was presented for analysis of composite plate panels. The test results were compared with those from the modal parameter identification method. It is shown that the former can give more accurate results.
