Sonic Cleaning Technology Sound Field Numerical Analysis And Simulation Studies

1970s, foreign sound waves used in power plant boiler cleaning,80s, sonic cleaning before everyone in the country began to be used in industrial cleaning and cognition. So far, experienced 30 years of development, research sonic cleaning applications has been quite extensive. Since the relative acoustic cleaning steam soot blowing, ball cleaning, mechanical cleaning and other traditional cleaning rapping there cleaning no dead ends, no-contact cleaning equipment cleaning surface without damage and many other advantages more widely used industrial production, and the majority of users of all ages. Although there are already a lot of sonic cleaning applied research, but research is relatively acoustic cleaning theory behind a lot.This paper combines sonic cleaning machine used in the gas compression equipment, the use of acoustic modules Virtual.lab acoustic finite element analysis software for gas pressure inside the fluid region acoustic sound field effect generator finite element simulation analysis, a preliminary study various factors affecting the normal condition of gas pressure machine acoustic sound field distribution inside the model of the sound field sound pressure points affecting the size of the case, and the sound generator manufacturer proposed empirical parameters to be optimized.Gas pressure machine through modal analysis and modal analysis of acoustic acoustic models were obtained natural frequencies and mode shapes with the acoustic model of gas pressure machine structure natural frequencies and sound pressure contours, through structural natural frequency and acoustic modal natural frequency comparison analysis, the possibility of acoustic coupling, and modal analysis of acoustic coupling, and finally get acoustic coupling modal natural frequency and sound pressure contours.Tune separately for internal fluid flow, sound generator installation location, acoustic coupling three factors on gas pressure inside the sound field distribution is analyzed to obtain the frequency response curve SPL and SPL with fluid stationary state frequency response curve comparison analysis, the impact of various factors on the optimal frequency sound generator and sound field distribution.According to the low-frequency sound generator acoustic cleaning empirical parameters chosen to broaden the scope of the internal gas pressure machine tune acoustic finite element analysis of the frequency range of gas pressure machine acoustic cleaning systems chosen sonic generator frequency parameter optimization, get conducive to achieving the ideal Refer to the cleaning effect of sonic generator frequency.Research carried out on the subject of gas pressure machine sonic cleaning technology for the engineering application of technology to provide a theoretical basis, while optimizing cleaning products sound generator provides an important reference, and uses this topic research methods, the same applies to research other equipment cleaning technology, the research results have universal significance.
