Vibrating Feeder Working Principles. Like other vibrating feeders, an electromagnetic vibrating feeder moves food by making the feeder tray shake. The item is put on the tray. When the tray vibrates, the object moves in a series of small jumps. The steady motion of the product comes from the way these hops work together.
The method using artificial external force is dealt with as dynamic testing hereinafter. Dynamic testing can be classified into three types, i.e. shaking table test, vibration generator test and free vibration test, as shown in Table 2. We need to use some equipment to apply external force to the target structure.
