Analysis of a Panel Contribution of a Vehicle Compartment Using the Acoustic Reciprocal Theorem

음향 상호성 이론을 이용한 승용차 차실 판넬의 기여도 해석

For a panel contribution of the passenger vehicle compartment, a model was created for acoustic analysis of the passenger vehicle compartment and through the acoustic normal modal analysis, frequencies and mode shapes of the resonance modes were calculated. Also, the contribution analysis of each panel was executed using acoustic reciprocal theorem, and through this analysis, normalized responses at the particular point indicate the relative contribution of each panel for generating noise and vibration
