Study on optimization of vehicle exhaust system noise and hook position based on multi-source experimental data analysis

Abstract

Article Highlights A multi-source experimental data analysis method is proposed to study the influence of exhaust system noise characteristics. This method is suitable for the study of system characteristics under the action of multiple factors, so as to accurately analyze the stability of system. If the influencing factors and their level numbers are selected reasonably, then the contribution of the influencing factors to the noise can be accurately evaluated from a quantitative perspective. In the next section, the current research status related to the paper is analyzed, summarizes the shortcomings of the current research, and points out the significance of the paper. Section 3 describes the composition and implementation scheme of the equipment system for the test. In Sect. 4, the calculation and analysis of multi-source test data are carried out, and the influence results of various factors on interior noise are obtained. The last section summarizes and prospects the future research contents.
