Abstract :
To optimize the traditional energy transmission where the slip ring abrades quickly and the spindle speed is not high enough in the rotary ultrasonic machining, the research is conducted on the non-contact power transmission system. Based on the principle of electromagnetic induction and Maxwell platform, the theoretical and the related simulation models of the mutual inductance of the non-contact power transmission system are established. A rotary electromagnetic coupling mechanism is then set up to verify those models. Through the simulation modeling and experiment verifying, the influencing factors on the transfer efficiency, such as the rotation speed, inter-stage magnetic gap, the ultrasonic frequency and resonance matching parameters have been investigated. As a result, the transfer efficiency at a high rotary speed can reach 80%, which provided a reference for the optimal design of the ultrasonic spindle.
