Acoustic Modal Characteristics of The Passenger Compartment-Trunk Coupled by Holes
- 발행 : 2000.11.16
초록
Acoustic modal characteristics are investigated on the passenger compartment and trunk coupled system. One-dimensional theoretical model is proposed and the validity of the model is verified by experiment on a simplified compartment model. The theoretical model identifies the occurrence of a new low frequency compartment mode, which does not exist in the uncoupled passenger compartment. The effect of the hole size on the compartment modes is analytically and experimentally examined.
