Hello, I need some help with setup/equipment used for a study to determine the natural frequencies on some small, lightweight samples (12in x 1.5in x .12 in.) in a catilever beam setup. The samples are made of carbon fiber and kevlar so they are fairly flexible to begin with. I am working on an undergrad thesis and I am very new to this type of testing.
I am currently trying to use the equipment that is already available to me: Impact hammer with signal conditioner and oscilloscope. I am wondering if this setup will yield accurate results or do I need something different for such a lightweight application.
There is also a shaker available to me with a computer and software but I opted to try the impact hammer first because the shaker, rated for 300lbs. of force seems much to large for these samples.
Any suggestions would be appreciated.
