An Inverse Method to Estimate the Properties of a Flexural Beam and the Corresponding Boundary Parameters

Abstract

This patent application discloses a method for estimating the properties of a flexural beam. The beam is shaken transverse to its longitudinal axis. Seven frequency domain transfer functions of displacement are measured at spaced apart locations along the beam. The seven transfer functions are combined to yield closed form values of the flexural wave number in propagation coefficients at any test frequency.
