OBJECT VIBRATION DEVICE, MOLD FOR SECONDARY CONCRETE PRODUCTS, AND METHOD FOR VIBRATING OBJECTS AND VIBRATING FEEDERS

摘要

Provided is an object vibration device that has a wide variety of applications and can produce a large vibration force using a small amount of vibration energy. Said vibration device has: a beam which has attachment sections, at two points along the length of the beam, for attaching to an object to be vibrated; and a vibrator affixed to a different part of the beam, in terms of the long direction thereof, from the attachment sections. The vibrator can vibrate at the characteristic frequency of the beam in the vibration device. When the vibrator runs at the characteristic frequency of the beam, the beam vibrates a large amount. The masses of the vibrator and the beam, which are undergoing vibrational acceleration, produce a vibrational force which acts on the target object, thereby vibrating the target object with a very large force.
