Comprehensive analysis of ball bearings involves a complex examination of parameters that affect the behavior of the bearing during operation. In particular, the influence of the rotational speed, clearance, load, and changes in elastic deformations on the dynamic characteristics of the bearing should be taken into account. In this paper, a model was developed in a general purpose software system based on the finite element method (FEM), which consists of a static and a dynamic model. Only part of the dynamic model related to explicit dynamic analysis will be presented in the paper. Explicit dynamic analysis provides changes in acceleration, velocity, displacement, and stress on bearing components over time, depending on external loads, clearance, and the bearing's rotational speed. In this work, the results for bearing 6006 will be presented.

摘要

Comprehensive analysis of ball bearings involves a complex examination of parameters that affect the behavior of the bearing during operation. In particular, the influence of the rotational speed, clearance, load, and changes in elastic deformations on the dynamic characteristics of the bearing should be taken into account. In this paper, a model was developed in a general purpose software system based on the finite element method (FEM), which consists of a static and a dynamic model. Only part of the dynamic model related to explicit dynamic analysis will be presented in the paper. Explicit dynamic analysis provides changes in acceleration, velocity, displacement, and stress on bearing components over time, depending on external loads, clearance, and the bearing's rotational speed. In this work, the results for bearing 6006 will be presented.
