    摘要： 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. The adapter helps to ensure that the ultrasonic transducer assembly vibrates with a simple axial motion when the work piece vibrates erratically.

    摘要： An ultrasonic welding system and method for joining first and second thermoplastic parts includes least one energy director formed on at least one surface of the first thermoplastic part, with the energy director projecting from the surface of the first thermoplastic part toward an opposed surface of the second thermoplastic part. The distal end portion of the energy director has a curved or flat surface that initially engages the opposed surface of the second thermoplastic part when the first and second parts are brought into engagement with each other. The first and second thermoplastic parts are ultrasonically welded by pressing the parts together while vibrating at least the first part in a direction parallel to the direction of projection of the energy director. The energy director may include a pair of substantially flat side walls joined to opposite ends of the curved or flat end surface.
