Fascicula de Inginerie %D 2010 %I Eftimie Murgu University of Resita %X The high energy ultrasound it is generated by piezoelectric elements which are excited from electric signal obtained from an electronic generator. The transmission of this high energy it is obtained by transmission element or concentrator element in function of what we want to do with this energy especial utilized in no conventional technology. The efficiency work is very important aspect because the energy utilizes has high values. In this paper it is presented methods to calculate the elements components necessary to generates and transmits the high ultrasound energy: piezoelectric transducers and transmission / concentrator elements. It is presented the experimental results obtained with the theory presented. Original contribution consists by method used and suggestive graphics for appreciation of variations parameters. %K ultrasound %K vibration %K propagation %K piezoelectric-transducer %U http://anale-ing.uem.ro/2010/11_C.pdf
