【摘要】：利用聲學(xué)仿真軟件Virtual.Lab對(duì)單擴(kuò)張腔和并聯(lián)多腔消聲器做了仿真分析,同時(shí)應(yīng)用數(shù)學(xué)工具計(jì)算得到了單擴(kuò)張腔在平面波理論下的傳遞損失。將單擴(kuò)張腔的仿真結(jié)果與理論傳遞損失作了對(duì)比,分析了高階模態(tài)波的傳播對(duì)于消聲器聲學(xué)性能的影響;又進(jìn)一步對(duì)比了多腔并聯(lián)消聲器與單擴(kuò)張腔的聲學(xué)性能。
[Abstract]:The acoustic simulation software Virtual.Lab is used to simulate and analyze the single expansion cavity and parallel multi-cavity muffler. At the same time, the transfer loss of a single expanded cavity under plane wave theory is calculated by using mathematical tools. The simulation results of a single expanded cavity are compared with the theoretical transfer loss, and the influence of the propagation of higher-order mode waves on the acoustic performance of the muffler is analyzed. The acoustic performance of parallel muffler with multi-cavity is compared with that of single expansion cavity.
