摘要
探讨了利用有限元法对燃料电池车整车车内噪声仿真分析计算的基本方法,包括乘坐室声学模态的分析、车身的结构模态计算以及整车结构声学耦合分析计算,并通过仿真分析找出了造成燃料电池轿车低频噪声大的原因。
The basic methods of simulation analysis on interior noise of a fuel cell car using finite element method (FEM) are discussed, including the acoustic modal analysis on passenger compartment, the calculation on structural modes of car body, and the analysis on structure-acoustic coupling. The simulation analysis reveals the causes of severe noise of fuel cell car at low frequencies.
