Optimum Support Damping for a Vibrating Beam.

Abstract:

A method for determining the optimum support damping of a flexibly supported cantilever beam using an analogous lumped mass model is described. The optimum system damping is determined as a function of rotational end-fixity of the cantilever support inteface. The damping value based on the lumped mass model is found to be in good agreement with the damping value based on a mathematical model of a continuous cantilever beam. Author
