基于FEM-BEM的轿车车内低频噪声综合分析方法
Integrated Analysis of Vehicle Cab Interior Noise in Low-frequency Range Using FEM-BEM Method
【摘要】 使用NASTRAN和SYSNOISE软件,采用FEM声固耦合及FEM-BEM耦合方法对轿车车内低频噪声进行分析,并根据车身板件贡献量分析结果提出合理的结构修改方案,改善车内特定检测点的噪声状况。
【Abstract】 The aim of the paper is to set up an integrated approach for a vehicle cab interior noise analysis using FEM structural-acoustic coupling and FEM-BEM integration method with NASTRAN and SYSNOISE software.Interior noise condition will be improved based on the result of panel contribution and reasonable structure modification.
