Description
Do you need to understand mechanical shock? Let’s commence in the time domain. First, consider an undamped 10 Hz fn SDoF system. (That is, its period T is 0.1 second). Subject it to three equal-height x half sine input pulses of durations T equal to
1 second,
0.1 second and
0.01 second.
Observe, in the first figure, that only when shock pulse duration T is close to a mechanical system’s period T is the response (y) likely to be damaging.
That statement is easy to understand for the ultra-simple SDoF system of that first figure, when it is subjected to those three ultra-simple shock pulses. But how does a designer (of vastly more complex structures) proceed if he is told that his product must survive field shocks represented by the vastly more complex-looking pulses at the bottom of that first figure. Our discussion has to include the frequency domain.
