摘要 A large-load ultrasonic vibration grinding system is designed.It is composed of a transducer,a cylindrical-conical horn,and a spoke-type grinding wheel.Firstly,the spoketype grinding wheel is equivalent to a composite model in which the hub is a cylindrical rod,the spoke and rim are medium-thick plates.Secondly,the frequency equation of the system is deduced using the continuous boundary conditions of each contact surface,the ultrasonic grinding system design is completed,and the acoustic vibration characteristics of the device are analyzed and verified.The experimental results show that the proposed model is effective for the design of large-load ultrasonic vibration grinding system.The ultrasonic system has a simple structure,stable acoustic vibration characteristics,and uniform displacement amplitude output.It is expected to be applied for large-load ultrasonic grinding.
