封闭式涡旋压缩机噪声特性仿真与声源定位研究
Research on noise characteristics simulation and sound source localization of closed scroll compressor
摘要
Abstract
In response to the complex internal structure and numerous components of enclosed compressors,the precise positioning and identification of resonant components are extremely difficult,which limits the efficient control of vibration and noise performance of vortex compressors.In order to rapid identify the noise sources of compressor,a acoustic and vibration coupling simulation analysis method for vortex compressor is proposed in this paper.The finite element simulation technology is employed to simulate the working process of the compressor rotor system,then the upper and lower support reaction forces are obtained.Add the forces inside the shell to calculate the surface vibration characteristics of the shell.Then LMS.Virtual.Lab software is used for acoustic simulation to clarify the noise characteristics radiated from the shell,while the experiment is also carried out to obtain the compressor noise spectrum.The results show that the measured noise spectrum is in good agreement with the simulation results.And the sound pressure level of compressor is 75.2 dB(A)with an error of about 2.4 dB(A)compared to simulation results.824 Hz and 1 940 Hz are the main noise sources of the compressor,corresponding to the moving vortex and stator shell components,respectively.Combined with the sound source recognition system,it can also be seen that the main sound source position of the compressor is also consistent with the simulation results.The research results can provide theoretical basis and technical reference for the localization and optimization of noise sources in enclosed scroll compressors.关键词
