摘要
Abstract
Sound package is one of the main ways to control interior noise of vehicles,and PBNR is an index comprehensively reflecting the sound insulation ability,sound absorption ability and sealing level of vehicles.A certain SUV is taken as the research object to test PBNR and SEA vehicle model simulation analysis and PBNR data comparison.Contribution analysis is conducted on SEA model to find out the weak parts,and the front circumference through hole,front windshield and front wall insulation pad are analyzed and optimized for the subsequent direction of sound package optimization.关键词
