Investigation of influence of acoustical contact on parameters of ultrasonic oscillatory system

Results of researches of influence of acoustical contacts between exchangeable operating tool and electro-acoustical transducer on mechanical and electrical characteristics of oscillatory system are presented in this article. Measured amplitude-frequency and phase-frequency dependence of oscillatory system with various types of operating tools are shown. Analyze of measured dependences is made. Searching of criteria of quality of acoustical contact is made. Usage of founded criteria allows preventing a damaging of ultrasonic technological device or its operation in the ineffective mode.
