Anti-vibration technology

Anti-vibration technology that supports quality and comfort in the machinery and equipment industry

What is anti-vibration?

"Vibration isolation" refers to preventing the transmission of vibrations generated by equipment (vibration sources) to the outside such as floors and walls. Effectiveness can be obtained by supporting a vibrating machine with an elastic body and insulating it from the outside.

Vibration isolation principle and vibration transmissibility

Anti-vibration rubber is used to provide anti-vibration support for machines that generate vibration, or to provide anti-vibration support to prevent external vibrations from affecting precision equipment.

As shown in Fig. (1), if the force transmitted to the foundation is F when the machine is supported by anti-vibration rubber, and the force when it is not supported is Fo, then the vibration transmissibility Tr is given by the following formula (1) is represented.

It has features such as the ability to select spring constants in three directions (up/down, left/right, and front/rear) with a single anti-vibration rubber, excellent internal damping, and small amplitude when resonating with equipment.
Because of the high degree of freedom in shape design, it is easy to install by bonding metal.
