摘要
对冰箱压缩机的进气消声器进行了实验及数值计算研究。以声波分解法为理论指导,搭建了消声器传递损失测试实验平台,测量进气消声器的传递损失。进而运用有限元方法,利用声学软件LMS Virtual.Lab对实验用消声器的传递损失进行数值计算,并与实验结果对比。结果表明:实验值与数值计算值吻合较好,数值模拟的准确性得到验证。
The experimental study and numerical simulation on the suction muffler of the refrigerator compressor were carried out in this paper.With the guidance of the acoustic decomposition method, an experimental system was built to measure the transmission loss of the suction muffler. Furthermore, the numerical calculations of the transmission loss were conducted using acoustic finite element software named LMS Virtaul.Lab. The results were compared with experimental results and show that the numerical calculation result agrees well with the experimental results, which verified the accuracy of the numerical simulation model.
