How do I Determine Input G-Loading Given Accelerometer Shock Response
How do I Determine Input G-Loading Given Accelerometer Shock Response
(OP)
I have shock response data (time) from a triaxial accelerometer. The task is to determine the shock load that the structure sees, using this response. I have the sampling rate and acelerometer specs. How do I begin to answer this question. I can reasonable assume that the system is a 1DOF system, obtain the transfer function and then do the inverse calculation to back out the input. Any thoughts?

The SRS has units of peak response accel (G) versus natural frequency (Hz). Damping is held as a constant, typically 5%, for this calculation. Furthermore, the calculation assumes a single-degree-of-freedom system.
So you will need an esimate of the natural frequency.
