Abstract: Ultrasonic transducer coupling adapters, ultrasonic transducer assemblies with an adapter, and methods for making and for using ultrasonic transducer adapter components are disclosed. An ultrasonic transducer assembly is disclosed for generating and transmitting ultrasonic energy to a work piece (e.g., non-resonant structures). The assembly includes piezoelectric actuators that generate ultrasonic vibrations in response to high-frequency electrical signals. A feedback system monitors and regulates voltages applied to the piezoelectric actuators. The assembly also includes an adapter that is connected to the piezoelectric actuators (e.g., via a front mass) and is configured to distribute the ultrasonic vibrations from the actuators to the work piece. The adapter reduces or substantially eliminates transmission back to the piezoelectric actuators of erratic strain generated by the work piece in response to these ultrasonic vibrations.
