Vehicle floor carpet acoustic optimisation using statistical energy analysis
Vehicle sound package and its effects on cabin acoustics involve complex analysis procedures. This paper gives some insights into various aspects of analysing and designing a new vehicle carpet system for improved acoustic performance, based on simulation. The defined simulation processes at material level, component level and vehicle level are illustrated. A full vehicle SEA model for acoustic package analysis is developed with focus on floor carpet system design optimisation, over cost and weight. New design concepts are proposed and validated. The Taguchi sensitivity analysis is conducted for cabin noise.
