Vibration Isolation and Isolation
Vibration isolation is a technology to reduce the transmission of vibration by inserting an elastic body (spring, rubber, etc.) between a vibration source and an area (floor, structure, peripheral equipment, etc.) where vibration is not to be transmitted.
For example, if a machine or other vibration-generating object is placed directly on the floor, the vibration will be transmitted directly to the floor. By placing an elastic material between them to support them softly, the vibration transmitted to the floor can be reduced.
Vibration isolation is a technology to reduce the transmission of vibration by means of elastic materials based on the same principle as vibration isolation. It is used to prevent the transmission of vibrations from the surrounding environment to precision equipment and other vibration-sensitive objects.
In other words, both measures are the same, but are differentiated by the direction in which the vibration is transmitted.
- Prevent vibration generated by the vibration source from being transmitted to the surrounding area ⇒ Vibration isolation
- Prevent vibration transmitted from the surrounding area from being transmitted to vibration-disgusting equipment, etc. ⇒ Vibration elimination

vibration control
Vibration control” is a technology that applies a brake directly to the object to suppress vibration, adding damping to make it less likely to shake.
The major difference is that vibration isolation reduces the transmission of vibration by providing elastic support between the vibration source and the object, whereas vibration control directly suppresses the vibration of the object.
As shown in Figure 4, the time axis shows that the vibration subsides earlier. Also, when viewed on the frequency axis, the peak of the vibration becomes smoother and the degree of amplification at the resonance frequency becomes smaller.
