how can i find dynamic stiffness valve between 200-300hz using (acceleration vs frequency) curve and dynamic stiffness curve plot in hyper graph.
Example:
using FRF (frequency response function) analysis
we plot (acceleration vs frequency) curve, frequency range: 1-2000HZ
dynamic stiffness curve plotted for 180kgf/mm
but my desire is to find the dynamic stiffness valve between 200-400HZ
is there any way to calculate the value in hypergraph for the desired range??

OS already outputs dynamic Stiffness.
try this discussion if you need to derivate it in HG:
