摘要
提出了一种用于车内低频噪声声源识别的理论分析方法。该方法摆脱了对试验的依赖 ,可用于车身结构低噪声优化设计 (或修改 )的迭代求解过程。分别采用所提方法和相关分析法 ,对某型国产轿车乘坐室内驾驶员右耳位置处的低频噪声主要来源进行识别 。
A new theoretical analysis approach for source identification of low frequency noise in an automobile passenger compartment is put forward, which gets rid of the dependence of experiments, thus can be applied in the iterative procedure of the low noise optimization design (or modification) of a passenger compartment structure. Then the main sources of the low frequency noise at the position of driver's right ear in the passenger compartment of a homemade saloon car are identified by means of the approach proposed and the correlation analysis, respectively. The calculated results compare well with those obtained by experiments.
