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. Also, reproduction of this pulse in an environmental test lab is usually straightforward. Eventually, the avionics component is integrated into a spacecraft.

Figure 5 shows the shock response spectrum corresponding to the example in Figure 4. 2 In contrast, the level at a center frequency in a random vibration power spectral density represents the average mean square level across the band. 3 Another shock response spectrum format is based on the relative displacement of the mass.
