Abstract

As an indispensable part of wind turbine, bearing block is subjected to alternating load or impact load for a long time, so it is very important to analyze its dynamic performance and vibration. In order to improve the vibration resistance of the structure, this paper relies on the powerful modal analysis function of ANSYS software. In the analysis, the finite element optimization method was used to analyze the main stress and ultimate strength of the main bearing block of the wind generator. Furthermore, the results are used to guide the optimization of bearing structure.
