Research on Thermal-Mechanical Coupling Modeling and Simulation of the Spindle Feed System of Machine Tool
College of Mechanical and Electrical Engineering, Nanjing University of Aeronautics and Astronautics, Nanjing, Jiangsu 210016, China
Performance of spindle feed system affects the accuracy of machine tools directly. Aiming at the problem that most research works focused on mechanical characteristics or thermal characteristics of the feed system so far, the thermal-mechanical coupling characteristic is studied in this paper. The coupling mechanism and theoretical model are established for a machine tool feed system, its coupling modal and harmonic response are simulated and analyzed by the FEM software. By comparing with the mechanical characteristics, thermal-mechanical coupling characteristics has directly influence on the dynamic performance of spindle feed system, its displacement amplitude is significantly weakened.
