摘要
利用互功率谱的方法对安装在混凝土地板上的小型排气扇工作时产生的转动结构声功率流进行了测量 。
Measurements of the rotational components are made by using the cross spectrum method for a small ventilation fan resiliently mounted on the concrete floors when the machine works. The structure borne power flows for different anti vibration mounts with different stiffness and different components are compared.
