摘　　要：利用模态分析中多点激振单点测响应的试验理论,提出搅拌桨的模态测试方法。对四斜叶搅拌桨进行了试验测试,并将所得测试数据与有限元计算结果进行了比较,结果基本一致。By using the fundamental theory of modal analysis, the method of modal measurement is derived and a way to measure the modal parameters of a pitched-blade turbine is given. Comparison of the results from modal analysis and finite element analysis shows that the natural frequencies are almost identical, indicating that modal measurement is a viable method for analysis of the natural frequency of a pitched-blade turbine.
