Free Vibration of Underdamped System, Structural Dynamics for Damped Free Vibration Example 1
Damped
Free Vibration
Example 1
The damped spring-mass system shown in the figure below has the following properties:
Mass, m = 0.0259 lb-sec^2/in
Stiffness, k = 20 lb/in
Damping Coefficient, c = 0.1 lb-sec/in
.
If the mass is suddenly released with zero initial velocity from an initial displacement of
2.0 in, find the maximum amplitude of free vibration of the mass after 5 and 20 oscillations.
