A rigid base has a shock load applied to it which loads a suspended mass.
Features:
Up to 4 damped springs can used. Each with their own spring-rate. A % critical damping ratio can be used that applies to all of the springs.
One of two dimensional unit systems can be used.
Shock pulses of 1/2 sine, triangular, sawtooth and rectangular step can be used with defined G load and pulse time.
The suspended box center acceleration is plotted as well as each spring force versus time. An active cursor can be used to see specific values. The simulation file can be exported to a CSV spreadsheet. A JSON file can also be created.
Verification Cases:
The system is drawn in a window that can be mouse zoomed and mouse rotated. It can also be mouse dragged by holding the shift key. Slider bars are available to adjust the animation amplitude and speed.
