What is low frequency vibration and what is the dividing line between high frequency and low frequency? Which vibrations are high frequency and which are low frequency?
date:2022-03-18 popularity:20 Collection

There is no strict distinction between high-frequency and low-frequency vibration, generally below 10Hz is low frequency, 10--1000Hz is medium frequency, and above 1000Hz is high frequency.

In the vibration isolation design, the interference vibration above 100Hz is usually called high-frequency vibration, the vibration of 6-100Hz is defined as medium-frequency vibration, and the vibration below 6Hz is low-frequency vibration.

Low frequencies: earthquakes, orbital vibrations

IF: car, generator

High frequency: high-speed rotating equipment, high-speed gears, rolling bearings
