摘　　要：本文通过对增压器压气机气流噪声的产生机理、传递路径分析和改善措施分别进行分析验证,针对性地从增压器匹配、标定、压气机设计、进气系统优化等多维度来对HISS噪声进行综合控制。基于该方法,可以有效地解决HISS噪声问题,而不需过多的采用被动的硬件隔音措施。本文关于增压器匹配和标定的分析,更是指出整机前期匹配的重要性,这些往往在实际开发中被忽视,从而浪费大量的开发资源。This article studies turbocharger aerodynamic noise phenomenon and fundamental、analyzes and validates transfer path,and control the hiss noise by different dimension such as turbo match、calibration、compressor design、intake system optimization etc.Based on these methods,it can practically solve hiss noise issue and doesn’t need passive noise isolation.Regarding the principal of turbo match and calibration,it also points out the importance of turbo-engine match at early stage.
