Abstract

The invention provides a vibration characteristic analysis method of a bearing, which comprises the following steps: establishing a split model of a bearing rolling body in three-dimensional drawing software, and establishing a solid model of the bearing in the three-dimensional drawing software; defining the entity model in finite element simulation software and establishing an assembly; carrying out substructure calculation on the assembly body in finite element simulation software and obtaining a plurality of flexible bodies; defining the plurality of flexible bodies in dynamic simulation software and establishing a dynamic model; the dynamic model is calculated in dynamic simulation software, and the inherent frequency of the dynamic model is obtained; after the technical scheme is adopted, compared with the prior art, the method has the advantages that the running state of the bearing can be accurately simulated, so that the resonance risk of the bearing can be checked according to the simulation result, the problems of vibration and noise can be timely avoided in the design stage of the bearing, and the reliability of the bearing is improved. And the bearing quality is effectively improved.

Description

technical field [0001] The present application relates to the technical field of electrical digital data processing, in particular to a vibration characteristic analysis method 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 power generators At the same time, the main bearing of the wind turbine transfers the energy captured by the wind rotor to the gearbox or generator, and the main bearing also plays an important role in supporting the wind rotor. [0003] The main bearings of wind turbines are subjected to high load intensity, complex load environment, and adverse effects such as environmental corrosion. Therefore, in the process of localization of large main bear...
