| Abstract: | Based on the deep analysis of noise character in locomotive loading test,a impedance composite muffler is designed.The muffler absorbs the excellence of the resistive structure and the dissipative structure.The resistive part of the muffler is composed of two section extended inlet structure.The dissipative part is composed of microperforated panel and sound absorption material.Two parts are assembled in order to obtain the optimal result. |
