Abstract


As people 's awareness of environmental protection , environmental protection washing machine by the majority of consumers . Ultrasonic cleaning is an environmentally friendly and excellent washing way , it has a wide range of applications in the field of China 's washing , a set of mature theory . Ultrasonic washing machine in China is lagging behind , based on this , the research presented in this dissertation . Ultrasonic washing machine main use of ultrasonic cavitation effect in the liquid to wash clothes , it is the core component of the transducer . Prevention and control of noise in the thesis material for rare earth magnetostrictive transducer design , as well as ultrasonic washing study , specifically the following aspects : 1 . Transducer designed to determine some of the basic parameters of the transducer , which the key is the calculation of the resonant frequency . 2 ultrasonic cleaning mechanism of the principles of the ultrasonic laundry analysis , draw some of the structural characteristics of the ultrasonic washing machine . 3 transducer mounting for the transducer mounting easily shedding phenomenon , the proposed idea of ??using screw connections ensure that the transducer within the life range of the washing machine are not detached . 4 . The cavitation noise prevention and treatment analysis of ultrasonic cleaning noise reasons put forward a variety of noise reduction , noise prevention measures .
