Vibration Damping

Subject

Damping an elastic system shifts its natural frequency away from its operational frequency and/or slows down the cyclically applied load by minimising dynamic amplification factors along with the associated stresses and strains.

Damping is normally applied to reciprocating machines (or parts thereof) to reduce vibrations caused by frequency attenuation. It is good design practice to install spacing materials that behave very differently to those used in the manufacture of a motor or generator mounting frame and/or its supports.

Calculator

Damping calculates the thickness of your damping material, that would be required to minimise vibration resonance in an elastic system (see Spring Coefficients) exposed to a cyclic force that would otherwise reduce fatigue life.

You define the damping ratio and the tensile modulus and strain limitations for the proposed support damping material and the damping calculator will provide its minimum cross-sectional area and thickness.
