【摘要】 本文针对水管路系统中噪声频率可能变化的情况,研究设计一种可调频的水管路脉动压力消声器,基于穿孔管消声器的半主动可调频水管路脉动压力消声器。文中用Ansys分别建立了消声器结构的实体模型,用声学软件Sysnoise对消声器的声学性能(传递损失)进行仿真模拟,并仿真分析了各结构参数对其声学性能的影响。更多还原

【Abstract】 Based on the changing of the noise frequency in the water pipe system,the pulsating pressure muffler is designed in the paper,which has a frequency modulation function,and this kind of muffler comes from the semi-active muffler,which also has a frequency modulation function.In this paper,the substantial model of the muffler structure is built by using Ansys,the muffler acoustics performance(transmission loss) is simulated by using Sysnoise.Meanwhile,the structural parameters on its acoustic properties is analyzed.更多还原
