자동차 흡배기계의 소음 저감 성능 향상에 관한 연구 : (공명기 적정위치 선정) (Selection of Optimal Position of a Resonator) = The Design Technique for Reducing the Intake Noise of Vehicle (Part I)

다국어 초록 (Multilingual Abstract)

The intake noise, a major source of vehicle noises, has rapidly becom a noticeable, and has been studied to reduce the level Traditionally, the intake system has been developed through a experiment, namely, the trial and error process. This approach requires very high cost and long time consuming to develop the system. Recently, FEM and BEM are becoming useful in analysis of the intake system, and the results of analysis are very valid. But because theses techniques also require high cost and long analysis time, these are generally not practical tool at the early stage of the development of an intake system. In this study, the software was developed to predict and analyze the acoustic characteristics of an intake system. It was based on the Transfer Matrix Method and operated to analyze a simplified intake system in a personal computer. It can be used early in the design stage of development of the intake system. This study presented an improvement to reduce the level of an intake noise. It was to select the optimum position of a resonator and verified by NIT/SYSNOISE, FE analysis commercial software, and testing a prototype.
