Dynamic Design of a High-Speed Motorized Spindle-Bearing System

摘要：

　　This technical brief presents a dynamic model based on the traditional transfer matrix method (TMM) and Jones-Harris nonlinear rolling bearing model to study the effects of the extended structure parameters on the vibration behavior of a high-speed motorized spindle-bearing system.The first critical speed and the dynamic stiffness of the high-speed motorized spindle-bearing system are systematically studied.A design sensitivity analysis of the structure parameters is then conducted to identify the main factor to affect the first critical speed of the spindle-bearing system.The results show that the processing condition, the shaft shoulder, the dimension of motor, and the bearing arrangement are sensitive to the spindle dynamic behavior.The TMM model of the spindle-bearing system is verified by measuring the high-speed motorized spindle overall dynamic stiffness.
