SRS Educational Animation


The following animation file is useful for demonstrating the Shock Response Spectrum (SRS) concept : HS_SRS.avi

Each system is subjected to a common base input which is a 1 G, 1 second half-sine pulse.

Each system has an amplification factor of Q=10.

The systems are arranged in order of ascending natural frequency.

Assume that each mass is the same.  Thus, the system on the far left has a soft spring, representing isolation.  The system on the right behaves nearly as a hard-mounted system relative to the input pulse.

The SRS is the peak response of each system as a function of natural frequency and damping.

The soft-mounted mass have very little absolute motion, but it has a high relative displacement and spring compression.

The hard-mounted system tracks the base input with nearly unity gain and will very little spring compression.

The middle systems have both high absolute and relative motion.
