Technical Glossary Natural Frequency and Vibration Damping

[Natural Frequency and Vibration Damping]

The ratio of vibration frequency f and the natural frequency f0 f/f0 is called the frequency ratio. To achieve effective vibration damping, the frequency ratio needs to exceed 1. The higher than 1 the frequency ratio is, the lower the transmitted vibration, and therefore the higher the vibration damping capacity of the material.
Hence it is important to keep the value of the natural frequency as low as possible. In this case, the natural frequency is the ratio of the spring constant of the vibration absorber to the load weight.
It is important to choose a vibration absorber with a spring constant appropriate to the load applied.
