Finite Element Analysis of Thermo-Mechanical Behavior of Spindle System Based on the Simplified Bearing Coupling Section
Spindle system is the most important component in machine tools to assure productivity and machining quality.The rotation of the spindle unit is made up of shaft,bearings and housings,and the heat and load generated during the rotation give a negative influence on the life and performance of the spindle unit.Existing method to predict the thermo-mechanical behavior of spindle system in machining requires heavy calculating cost due to the complex geometry as well as the thermo-mechanical properties of bearings.This paper presents the simplified bearing coupling section model to predict the thermo-mechanical behavior of spindle system during rotation.Matrix27 element is adapted to substitute stiffness and damping characteristics of the angular contact ball bearing.Thermal conductance coefficients between the inner and outer rings of bearing were decided to demonstrate thermal characteristics of angular contact ball bearings.Experiments were conducted with measuring temperature and deformation of spindle to verify the simulation in several preload conditions.
