In Single Degree of Freedom vibration with harmonic support motion, I have used an accelerometer to measure acceleration of the vibrating system. The frequency of the support motion is sweeped through in order to find the resonant natural frequency of the system. So in tabular form I have frequency data and acceleration data. How do I find displacement from this data?
I figured you have to integrate twice...but time is not a variable. so i don't know what to integrate.
