This is an online calculator for the theoretical shock response to a base input. It has pre-coded
options for 1/2 sine, triangular, rectangular and saw-tooth pulses where peak amplitude in g's and
time pulse in seconds are input. It also has an option for a user input spectrum with up to 20 time
points. The suspended system includes the suspended weight on a linear spring (k) and viscous
damper (c). A gravitational constant is also needed. Any consistent set of units with seconds and
cycles per second (Hz)are required.
Output includes a chart of the input shock and shock response versus time. The undamped
natural frequency, critical damping ratio and peak response-to-peak input are also output.
