Simulation of Spindle Units Running on Rolling Bearings

This paper presents a general approach to solution of the complex simulation problem of spindle units (SUs) running on rolling bearings (ball bearings and roller bearings) and proves the necessity of making a complex analysis of their nonlinear tribo-mechanical properties at the development stage. For doing this, we apply SU beam analytical diagrams and develop a complex mathematical model of SUs, which incorporates theparticular models, e.g. elastic-deformation, dynamic and heat models, and the model of the bearing fatigue life. To facilitate practical analysis in design, we develop software and demonstrate its application by examples of the comparative analysis the typical structures of SUs.
