摘要
Abstract
A finite element model was built to simulate the inner sound field of muffler ,based on the simulation of the conditions as much as possible,calculation the transmission loss by numerical analysis.Then,a number of effects were studied to obtain the optimal combination.Based on the test technique of standing wave tube with double microphones,a four sensor method was developed to measure the transmission loss.The transition of the tapered pipe was used to solve the size inconformity between muffler aperture and standing wave tube diameter,then get rid of the influence of the tapered pipe,the transmission loss of muffler itself was obtained. The experimental results and numerical simulation results have good consistency.关键词
