| description | This paper investigates rotating magnetostrictive ultrasonic transducers (RMUT) with eddy current losses to enhance the stability requirements of high-power ultrasonic vibration processing in defense and military industries. A nonlinear amplitude prediction model for RMUT has been developed by integrating the ultrasonic excitation system with magnetostriction and magnetization phenomena based on the substructure system's ultrasonic vibration transmission characteristics and laws. By delving into the mechanism of energy conversion and dynamic characteristics of eddy current loss in ultrasonic vibration systems, the influence of eddy losses on RMUT's output amplitude and frequency stability can be unveiled. Simulations and experiments have been conducted to verify the nonlinear prediction model with a given loss structure. Verifications show that the mechanical quality factor of RMUT can be adjusted to achieve strength-toughness matching of vibration energy in terms of internal structure by modifying the heat loss of the excitation system. Especially, radially slit treatments (RS) led to a higher mechanical quality factor and larger vibration amplitude, while radially sliced treatments (RSE) resulted in a higher energy transfer characteristic. Compared to the RSE structure, RS exhibits a 218% decrease in stability and a 47.1% increase in amplitude. |
