A vibration isolator is a device used to prevent vibrations transmitted from the ground, foundation, floor, or other surrounding areas from being transmitted to the equipment.
Vibration isolation is used separately from vibration damping, which prevents vibrations generated by equipment from being transmitted to surrounding equipment.
There are two methods of vibration prevention/suppression: one uses elastic materials such as rubber or dampers, and the other uses fluids such as air or oil.
There are two types of vibration isolators: passive vibration isolators, which suppress and prevent vibrations from the surrounding environment, and ATEP vibration isolators, which use sensors and actuators to dampen weekly vibrations.
Vibration isolators are used to eliminate the effects of vibrations from the external environment in order to ensure accurate equipment operation.
Minimizing the effects of vibration is essential for micron-order processing and measurement in precision measuring instruments, semiconductor and liquid crystal manufacturing inspection equipment, and ultra-precision processing machines.
In recent years, technological advances have not only increased the required component precision, but research and development of devices with vibration frequencies lower than those of nanotechnology and other technologies have made the elimination of vibration by vibration isolation even more important.
The simplest principle of vibration isolation is based on the pendulum model.
If a pendulum is moved slowly and widely, it will swing widely, but if it is moved quickly and finely, it will hardly move at all.
Passive vibration isolators use this pendulum model to suppress external vibration by placing an elastic body or fluid between the pendulum model and the device.
In contrast, in an active vibration isolator, a sensor fixed to the floor or other surface constantly senses external vibrations and generates vibrations through an actuator that has a frequency opposite to that of the sensor. The external vibration and the vibration generated by the anti-vibration table cancel each other out, allowing the equipment to remain stationary.
The control method can also be divided into feedback control, in which the vibration of the equipment or vibration isolator is detected by a sensor, and feed-forward control, in which the vibration of the floor or ground is detected.
Neither is superior to the other, and the most appropriate method should be selected based on the purpose of use, the surrounding environment, and the natural frequency of vibration.
