摘    要:建立了压缩机消声器内部声场的三维有限元模型,该模型考虑了压缩机消声器结构和边界条件方面的特殊性,可以计算压缩机消声器的传声损失。同时,将双传声器驻波管测量材料声阻抗的原理,推广到四传声器法测量压缩机消声器的传声损失。通过用单节膨胀消声器的验证,以及在某型压缩机消声器的数值解析和试验分析表明:本文采用的数值计算方法和建立传声损失测试装置是可以应用于压缩机消声器这种复杂对象的。

关 键 词:消声器  压缩机  驻波管  声阻抗  声场  数值计算方法  传声器  试验分析  数值分析  三维有限元模型

Abstract:A Finite Element Model is suggested to simulate the inner sound field of muffler, by which the transmission loss of the muffler can be calculated. Based on the test technique of standing wave tube with double microphones, a four-sensor method is developed. A single expanded tube specimen is used to verify the precision of FEM model and test technique in analyzing the muffler transmission loss, and the results of simulation and experiment agree nicely with the theory solution. Then, the FEM model and test technique are applied for analyzing the transmission loss of the muffler for some compressors.
Keywords:compressor  muffler  transmission loss  standing wave tube  FEM
