Vibration Damping vs. Vibration Isolation

Divider

Pad Pak and Pad Sheet materials are crafted from highly developed elastomers, designed to prevent problems created by excessive vibration and structure-borne noise.

Note Vibration Damping pads (D & 700 series) are used to reduce damaging internal vibrations in very heavy machinery. (Ex: Stamping and Printing Presses, etc.) See photo example below.

Note Vibration Isolation pads (B & 400 series) are used to protect lighter, more sensitive equipment (Ex: Microscope in a Lab) from external vibrations, OR they can be used to minimize low-frequency, structure-borne noise generation.

All Pad materials are RoHS & REACH certified and provide very good resistance to many chemicals, lubricants and fuels.

The most important terms in vibration engineering are frequency “f”, amplitude “A” and damping “D”.

  • Frequency “f” is a measure of the number of complete vibration cycles per second. (Low frequencies are generally what we call mechanical vibrations.)

  • The amplitude “A” is the vibration wave range around its equilibrium. It determines the severity of vibration and is usually expressed in terms of acceleration or displacement.

  • Damping “D” designates the measure of amplitude reduction of the vibration of a freely oscillating spring-mass system through friction. Damping refers to the conversion of energy to heat.
