VIBRATION STUDIES

HELLO, TRYING TO SIMULATE VIBRATION STUDIES USING SOLIDWORKS/COSMO
THE STUDIES WE RECEIVE SHOW CHARTS WITH ACCERLATION VS FREQUENCY
ACCERLATION BEING "g" VS THE FREQUENCY
BASICALLY WHAT WE ARE TRYING TO DO IS SIMULATE A A FIXTURE BEING SUBJECTED TO A SINUSOIDAL VIBRATION AT ALL FREQUENCIES FRO 10HZ TO 200 HZ , THIS BAND OF FREQUENCIES IS LOGARITHMICALLY SWEPT OVER A DURATION OF 3 MINUTES AT A ACCERLATION OF 1 (G)
AFTER THAT IS PERFORMED I NEED TO DETERMINE IF THERE IS A RESONANT FREQUENCY ABOVE OR BELOW 200

I'VE BEEN TRYTING TO DO A DYNAMIC FREQUENCY STUDY USING MODAL, HARMONIC & / OR RANDOM VIBRATION
BUT I CANT GET EXACTLY WHAT I'M LOOKING FOR
ANY HELP OR SUGGECTIONS WOULD BE VERY MUCH APPRECIATED
