| Abstract: | A coupling analysis model of thermal and dynamic characteristics was built for the high-speed motorized spindle. In the model, the thermal contact resistance of joints and the effect of the lubricant viscosity variation with temperature were considered, the radial stiffness function of the bearing was described by a quasi-static model of bearing. The variation of the supporting stiffness under the combined action of the softening effect of bearing centrifugal force and the hardening effect of thermally indu... |
