Spring Mass System
To determine the damping coefficient of a single-degree of freedom system.
The experimental set up consists of
- Spring Mass Test rig- with frame, Mass and Spring.
- Signal Conditioner.
- Computer based data acquisition system
Purpose: To Estimate of Damping Ratio:
The logarithmic decrement is estimated from the expression
Ϭ= (1/n) log (A1/An)
Damping ratio ε= / (2π)
