Simulation and Optimization to Vehicle Interior Noise in Mid and High Frequency Using VAone

Abstract

Finite Element-Statistical Energy Analysis (FE-SEA) hybrid method is better than SEA method for vehicle interior noise analysis in mid frequency. The noise predictions using FE-SEA in mid and SEA in high frequency are good in consistent with the experiments, so the computer-aided simulation using above two methods is a good alternative to experiments. The results shows that the Poly Methyl Meth Acrylate (PMMA) instead of glass as the windshield material can reduce the interior noise at the driver’s ear in mid frequency, also lighten the body weight. The results shows the new polymer transparent material can looked as a good new way for vehicle interior noise reduction and body lightweighting.
