飞机舱内中频噪声的FE-SEA混合法预测及验证
Prediction and Validation of Aircraft Cabin Noise by Hybrid FE-SEA Method at Mid-frequency Range
摘要
Abstract
Prediction and experimental verification of aircraft cabin noise modeled by the hybrid FE-SEA method is carried out. The method of subsystem dividing of the cabin is introduced. The cabin's noise spectrums in mid-frequency range under 4 different excitation conditions are simulated and thereafter compared with measurement results. It is shown that the hybrid FE-SEA method based approach is more accurate than the conventional Statistical Energy Analysis (SEA) method in predicting mid-frequency noise inside the aircraft cabin.关键词
