摘要
本文运用统计能量分析软件VA One对某轿车建立声学计算模型,预测140km/h和110km/h速度下车辆的空气动力性噪声对车内的影响。车内前后排噪声的预测结果与风洞试验实测结果进行了比较。同时还对车辆的总体隔声量也进行了预测计算,并与混响室内的实测结果进行比较。结果表明所建立的计算模型可以准确预测气动噪声对车内噪声的影响,预测精度为3d B以内。
An acoustical calculation model of a car is built with the SEA(Statistical Energy Analysis) software VA One. The model can forecast the effects that the aerodynamic noise has on the noise level inside the car under the speed of 140km/h and 110km/h. The comparison between the forecasting noise level results of the front seats and back seats inside the car and the ones measured in the wind tunnel experiments has been made. Besides, the total sound insulation of the car is forecasted, and compared with the results measured in the reverberation chamber. The results indicate that the calculation model can forecast the effects the aerodynamic noise has on the noise level inside the car accurately with the accuracy less than 3d B.
