摘要
Abstract
This paper had used a blade natural frequency measurement system to test the natural frequency of turbine blade. On the basis of the theory of modal analysis and finite element method,dynamic performance analysis of turbine blade was redearched by adopting the Hypermesh and Abaqus joint simulation method. Comparing the blade in the first three orders natural frequency calculated value and experimental value, good results were obtained.关键词
