Research on correlation model between transducer temperature and acoustic performance parameters of ultrasonic machining system

In the process of ultrasonic vibration cutting (UVC), acoustic performance parameters machining system change because systems heating up and loads. The changes will affect resonant frequency, impedance, power match system, stability amplitude UVC system. It is hard to monitor online. Based on analysis correlation mechanism between transducer temperature parameters, models resonance static capacitance, dynamic resistance are established by curve regression modeling method. an determined using models. effectiveness model verified experiments. gives information for evaluation process, impedance matching adjustment supply.
