This responsive Processing-based applet allows the user to vary the inputs to see how these effect a damped single degree of freedom system.
The damping ratio should be entered in decimal format (e.g. 5% = 0.05)
'Total time' controls the horizontal width of the graph. Decreasing 'Time step' provides a more accurate result, but the system's processing power must be considered.
| Vibration mode | |
| Mass | kg |
| Stiffness | N/m |
| Damping ratio | |
| Initial displacement | m |
| Initial velocity | m/s |
| Harmonic force | N |
| Harmonic frequency | rad/s |
| Total time | s |
| Time step | s |
Maximum positive displacement = m
Maximum negative displacement = m
