and experience their maximum acceleration levels when the input is already finished.
Figure 34 plots the relative displacement the springs need to endure during the event
and afterwards; this illustrates that if you go the route of a damper, you need to ensure
it has enough spring compression available for your environment.
Figure 33: Response from different springs for the given base input of 1g, 1 second half sine
pulse.
Figure 34: The absolute value of the relative displacement between the masses and the base
input is plotted on a logarithmic scale to illustrate the much larger spring compression that the
softer springs need to endure.
