First, the spoke-type grinding wheel was equivalent to a composite model where the wheel hub is a cylindrical rod, while the spokes and rim are medium-thick plates. The frequency equation of the system was derived based on the boundary continuity conditions of each contact surface, and the design of the ultrasonic grinding system was completed. An experimental setup was fabricated, and its acoustic and vibration characteristics were analyzed and verified. Experimental results demonstrate that solving the system frequency equation via the spoke-type grinding wheel composite model is effective in addressing the design challenges of high-load ultrasonic vibration grinding systems. This ultrasonic system has a simple structure, stable acoustic and vibration characteristics, and can output uniform displacement amplitude, showing promising application prospects in the field of high-load ultrasonic grinding.
