【摘要】：利用二维解析方法研究两腔抗性消声器的声学性能。通过正交试验设计分析消声器进出口管半径、扩张腔半径、隔板通孔半径以及隔板位置结构参数影响消声器传递损失的主次关系,进而基于均匀设计的试验数据经回归分析获得了两腔抗性消声器传递损失预估模型。结果表明,在1 000~3 000 Hz中频段内,对传递损失影响最大是扩张腔的半径,其次是隔板通孔的半径、隔板位置,最后是进、出口管的半径;该文建立的传递损失预估模型可根据消声器结构参数准确预估抗性消声器的传递损失,能直接反映消声器传递损失与结构参数的关系。该研究为快速优化设计消声器提供了参考。
[Abstract]:The acoustic performance of two-cavity resistant muffler was studied by two-dimensional analytical method. The main and secondary relationships of muffler transfer loss are analyzed by orthogonal design, such as the radius of muffler inlet and outlet tube, the radius of expanding cavity, the radius of through hole of diaphragm, and the structure parameters of diaphragm. Based on the experimental data of uniform design, a model for predicting the transmission loss of a two-cavity resistant muffler is obtained by regression analysis. The results show that in the frequency range of 1 000 ~ 3 000 Hz, the radius of the expansion cavity is the largest, the radius of the through hole of the diaphragm, the location of the partition, and the radius of the inlet and outlet tube are the second. The transfer loss prediction model established in this paper can accurately estimate the transfer loss of the resistant muffler according to the structural parameters of the muffler and can directly reflect the relationship between the transmission loss of the muffler and the structural parameters. This study provides a reference for rapid optimization design of muffler.
