Analysis of transfer matrix of non-uniform beam based on finite element method

To calculate transfer matrix of the plane non-uniform pure bending beam by transfer matrix method of multibody system quickly and efficiently, the stiffness matrix of the beam was calculated by the finite element method firstly, and then the transfer matrix of the beam was calculated. It was proved by the example that this method is effective and feasible. And it provided a new idea to solve the problem of complex system dynamics by combining finite element method and transfer matrix method of multibody system.
