Rare Earth Magnetostrictive Transducer Device Environmentally Friendly Washing Machine

Along with the people environmental protection consciousness enhancement, each kind of environmental protection washer has received as the general consumers' favour. The ultrasonic cleaning is a most washing way of environmental protection. It has the wide spread application in the cleaning domain of our country, ant has a set of mature theories. The research of our country ultrasonic washer is relative lag. Based on this, the paper content is presented.The ultrasonic washer uses cavitation effect for washing the clothing . Its core part is a transducer. In the paper, the design of giant magnetostrictive supersonic transducer, and some advice that reduce cavitation noise has been analized. The concrete content is as follows:1. The design of the transducer. Define some basic parameters of the transducer. And the key is the computation of the resonance frequency.2. The theory of ultrasonic cleaning. The theory of ultrasonic has been analized.Then we can get some structive features of the ultrasonic wave washer.3. The installment of the transducers. In order to ruduce happenning the phenomenon that the transducer easily falls off, The conception of the bold fastening has been taken,which can guarantee that the transducers don't fall off in the washer's nature life.4. Cavitation noises preventing and controlling. Analyse the reason that ultrasonic cleaning has the cavitation noise, and give some adveices that reduce chirp, guard against chirp.
