Is there any device existing to measure the damping ratio of a spring or any structure? I would be glad to receive any reference document or papers.
I am not sure if there is a special device for that. But, instead, you can obtain the Bode diagram, which you might then use to find the damping ratio. Obtaining Bode diagrams is very practical and easy.
