Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] In the prior art, the empirical formula calculation method ignores some influencing factors, resulting in a certain error between the calculation result and the actual situation. The theoretical calculation method considers more comprehensive factors, but they are all based on the Hertzian contact theory, which cannot accurately describe the shape change of the contact area, and the calculation process is very complicated, and there are some deviations b...

Abstract

The invention discloses a ball bearing rolling body modeling method and system and a storage medium, a one-dimensional beam unit and three-dimensional hexahedron coupling modeling method is adopted, and a rolling body is divided into an internal region and an external region. Wherein the outer region adopts a three-dimensional hexahedron for modeling, the inner region adopts a one-dimensional beam unit for simplified modeling, and the three-dimensional hexahedron of the outer region and the one-dimensional beam unit of the inner region adopt a common node method for modeling. According to the modeling method, the unit number of the finite part model of the ball bearing rolling body is effectively reduced, the finite part modeling method of the rolling body is simplified, and the unit quality of the rolling body is ensured. The method has the advantages of simple and quick modeling, few units, high precision and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to a modeling method, system and storage medium of a rolling body of a ball bearing. Background technique [0002] As an important key basic component, the ball bearing's working performance and service life directly determine the working performance and service life of mechanical equipment. With the development of mechanical equipment in the direction of high speed, heavy load, high precision and long life, the requirements for the working performance, precision and reliability of ball bearings are also increasing. The contact characteristics between ball bearing components are directly related to the operating characteristics of the ball bearing. Therefore, it is of great significance to accurately calculate the contact characteristics between the ball bearing rolling element and the raceway in the design stage for the prediction of the ball bearing operating characteri...
