Abstract
The vibration characteristic of turbine’s blades is an important influencing factor affecting the turbine safety. In this paper, a three-dimensional finite element model of a turbine’s blade is built and the vibration of the blade is analyzed under the prestressed condition. Influence of operation speed and structure of the impeller on the blade’s vibration character-istic is discussed, and the results are comparatively analyzed. By analyzing the change of the vibration frequency of the blade, the main frequency range in which the speed and structure of the impeller have large influence on the blade’s vibra-tion is obtained. This work has provided a reference for analysis and design of the turbine’s blades by means of the finite ele-ment method.关键词
