Research Of The Vibration And Noise In Self Saturated Reactor

At present, more and more people attention noise pollution, as our electrician class in terms of graduate students, Study the source of electrical equipment noise, find the corresponding relationship between electromagnetic vibration and noise, making noise estimation method and put forward the new method for reduce noise of the electric equipment will also be key jobs for electrical researchers.This paper introduces the theory of vibration and noise theory, acoustic wave equation was deduced in detail. Secondly calculate the Self Saturated Reactor radiation noise, vibration analysis of the main noise source. Main job has a single slice of silicon steel sheet vibration mechanics model analysis, single pile of silicon steel sheet iron core vibration mechanical model is derived, and calculate the source(Self Saturated Reactor) vibration noise, and its radiation in air noise calculation. Then using the simulation software and experimental equipment to measure Self Saturated Reactor excitation current source size and the size of the corresponding relationship the vibration noise radiation.Finally, put forward a kind of piezoelectric materials in active noise control scheme. Based theoretical calculation based on sound propagation based on piezoelectric materials is obtained under the condition of the reflected sound waves to zero, the incident sound wave frequency and power force applied on the piezoelectric material. Through the use of noise-electric analogy method analysis of piezoelectric materials active sound absorption technology, it is concluded that under the condition of zero reflection waves, the incident sound wave frequency and voltage amplitude and phase on the piezoelectric material corresponding relation.
