AN INTRODUCTION TO THE SHOCK RESPONSE SPECTRUM - …
1 AN INTRODUCTION TO THE SHOCK RESPONSE SPECTRUM Revision S By Tom Irvine Email: July 9, 2012 _____ INTRODUCTION Spacecraft and launch vehicle components encounter mechanical SHOCK from a variety of sources. Components must be designed and tested accordingly to ensure reliability. For example, engineers must anticipate transportation and shipping SHOCK . Consider an avionics component encased in foam packing material inside a shipping container. The container is placed on a truck which runs over a speed bump or a railroad track at an imprudent speed. The avionics component may receive a half-sine SHOCK pulse. This type of pulse can be readily represented in the time domain by its duration and peak amplitude.
