Vibration damping: What's the difference between passive ...

Passive and active methods of vibration damping (or vibration isolation) differ in the way they respond to and manage vibrations. An easy way to distinguish between the two is that passive systems use simple mechanical devices, fluids, or elastomeric materials, whereas active vibration damping relies on a closed-loop system with feedback.

Vibration Isolation Theory | LORD Corp

Vibration is an oscillatory motion. Any body with mass and elasticity can vibrate. The simplest type of vibrating system is called a single-degree-of-freedom spring-mass system. The spring is characterized by its spring rate, K, and a mass, M. This system is called a single-degree-of-freedom system because motion can occur in only one direction.
