"Simple" Fequency Experiment On Bone (Advice Needed Please)
Hi All,
Great Site.
I am trying to find the Resonant Frequency (Natural Frequency) of a Sheep Tibia using an Electromagnetic shaker with an Impedance Head attached as well as an Accelerometer mounted on the opposite end of the Bone to monitor the output repsonse.
I am currently not having great luck in acheiving what i am looking for.
I am holding the bone in a Free-Free end condition, and with a Single Degree Of Freedom. Exciting one end of the bone using the shaker. Obtaining the the response at the opposite end. I was hoping to be able to calculate some sort of transfer function for the Bone (system)
I am using Bruel&Kjaer Labshop as my Hardware & Software which displays both the Time & Frequency domain on screen as i vary the excitation signal (Stepped Sine Wave) .
Is it possible to Calculate this Transfer Function? / Find the Natural Frequency ? / Observe when the bone is appraoching its Natural Frequency on screen ?
Most appreciative for any Help
Kind Regards
