豪华大客车车内声场的模态分析

Modal Analysis of Interior Acoustic Field of Saloon Car

结合典型豪华大客车采用有限元法进行了车内声场的模态分析。文中对内部纯流体声场,考虑座椅影响和考虑声场与车身结构之间耦合作用这三种情况分别建立了车内部声场的三维有限元计算模型,并对车内声场进行了声学的模态分析。

Based on the finite element method, modal analysis of car＇s interior acoustic field is analyzed. In this paper, the interior acoustic field＇s FEM models of saloon car are bulk by the three circumstances, simulating interior acoustics field, calculating the space of seats and calculating the coupling between structure and acoustics. Saloon car＇s modal analysis of interior acoustic field is also analyzed.
