Mathematical Modelling of a Coefficient of Nonlinearity in Dynamics of Deep Groove Ball Bearing with Damage

The presented research is a part of a comprehensive research of nonlinear dynamic behaviour of rolling bearings, which are the parts of all rotating assemblies and machinery. In accordance with the state-of-the-art requirements for advanced mechanical design and industrial digitalization, extensive experimental and mathematical research is performed, and a new mathematical model for the dynamic behaviour of rolling bearings with damages is developed. The results obtained for a particular type of deep groove ball bearings are presented in this chapter, and the possible further research and implementation of the obtained model in digitalized self-monitoring systems is discussed.
