摘要
The complicated electromechanical coupling is existed in a motorized spindle system. If the electromechanical parameters of the system are not matched well, electromechanical coupling vibration will be caused. The system stability and work-piece surface quality are decreased. The dynamic analysis method, which both motor and mechanical characteristics of a spindle system are separated, is adopted for being difficult to make the effective analysis and evaluation of electromechanical coupling vibration for the system, and achieve optimization match for electromechanical characteristics of the system. The analysis method for match characteristics of the system is proposed based on the electromechanical coupling dynamic model. The proposed method is used to study effects of working parameters of an inverter, electromagnetic design parameters of a spindle motor, and grinding wheel mechanical parameters on ripple torque and stator current spectrum. The experiment is also performed. The physical mechanism of electromechanical coupling vibration in the system is revealed. The method is proposed to suppress electromechanical coupling vibration by optimizing working parameters of an inverter, electromagnetic design parameters of a spindle motor, and grinding wheel parameters. It is theoretically and experimentally validated that electromechanical coupling vibration is effectively suppressed by optimizing working parameters of an inverter. The match characteristics of the system and grinding surface quality are improved. Furthermore, the proposed analysis method based on the electromechanical coupling dynamic model is effective and feasible. © 2012 Journal of Mechanical Engineering.
