Modal analysis and influence law of a wind turbine main shaft

A finite element model was established and modal analysis was performed on a wind turbine main shaft. By adjusting the length of the expansion sleeve, the effect of the length of the expansion sleeve on the natural frequency of the wind turbine shaft was summarized. The results show that the greater...

Description
Summary:A finite element model was established and modal analysis was performed on a wind turbine main shaft. By adjusting the length of the expansion sleeve, the effect of the length of the expansion sleeve on the natural frequency of the wind turbine shaft was summarized. The results show that the greater the length of the expansion sleeve, the greater the natural frequency of the wind turbine shaft.
