Abstract

This application proposes a method for analyzing the vibration characteristics of a bearing, which includes: establishing a split model of the rolling body of the bearing in the three-dimensional drawing software, establishing a solid model of the bearing in the three-dimensional drawing software; defining the solid model in the finite element simulation software and Establish an assembly; calculate the substructure of the assembly in the finite element simulation software and obtain multiple flexible bodies; define multiple flexible bodies in the dynamic simulation software and establish a dynamic model; The natural frequency of the dynamic model is obtained by calculating the natural frequency of the dynamic model; judging the resonance risk of the bearing according to the natural frequency. After adopting the above technical scheme, the advantages of this application compared with related technologies are: the operating state of the bearing can be accurately simulated , so as to check the resonance risk of the bearing according to the simulation results, so that the bearing can avoid vibration and noise problems in time during the design stage, and effectively improve the quality of the bearing.

Description

technical field [0001] The present application relates to the technical field of electrical digital data processing, and in particular, to a method for analyzing vibration characteristics of a bearing. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during the movement of the mechanical rotating body, and ensure the rotation accuracy of the mechanical rotating body. Among them, bearings are used in wind turbines. At the same time, the main bearing of the wind turbine transmits the energy captured by the wind wheel to the gearbox or generator, and the main bearing also plays an important role in supporting the wind wheel. [0003] The main bearing of the wind turbine has high load strength, complex load environment, and adverse effects such as environmental corrosion. Therefore, in the process of localization of large-scale main bearin...
