Paper Title:
Time Domain Identification of Distributed Dynamic Load of Rotating Timoshenko Beam Based on Orthogonal Polynomial
  Abstract

Based on the theory of two-dimensional (2-D) orthogonal polynomials, the function of dynamic load is fit by using the primary functions sequence. The identification of the distributed dynamic load can be transformed into the solution of the fitting coefficients. For the finite element model of the rotating Timoshenko beam, the unknown distributed force is identified by the load identification theory of the continuous beam in time domain. Numerical simulation shows that the method is precise as long as enough data of feedback points are collected; and it is simple and effective for engineering applications.
