摘要
提出了一种新的“声学泄漏边界条件” ,并将其引入到声振耦合分析的有限元模型中 ,使模型具备了对实际车辆乘坐室声学泄漏问题的处理能力。然后以SH76 0A型轿车乘坐室为对象给出了算例 ,并通过计算和测量结果的对比分析 ,验证了所提方法的正确性。
A new'acoustic leakage boundary condition'is put forward,and an improving finite element model,which can deal with the acoustic leakage problem of the actual passenger compartments,is given by means of introducing this kind of boundary condition.Then an example for the passenger compartment of saloon car type SH760A is solved.And the correctness of the method given here is validated by contrast analysis between the calculated results and those obtained experimentally.
