- Aerospace pyrotechnic shock response spectrum (SRS) specifications are almost always given with an amplification factor Q=10
- Corresponding time history waveforms for the base input acceleration are almost never given with the specifications
- Users are allowed to synthesize their own waveforms to satisfy the SRS for analysis & test purposes
- Some shock analysis methods use the SRS directly without time history synthesis, such as modal combination methods
- The following method enables an SRS specification to be converted to a new Q value for engineering purposes
