Abstract:
Transfer matrix of space non-uniform beam element is deduced using finite element method in this paper.When stiffness matrix of space non-uniform beam element is deduced,a new displacement named axial tension and compression strain is introduced to increase the degree of axial displacement interpolating function.Stiffness matrix of space non-uniform beam element is calculated according to higher-degree polynomial interpolating function,and transfer matrix of the beam is obtained by matrix transforming.The deflection and modal of beam are calculated based on the transfer matrix.The calculation results prove that this method has highly calculating precision,and it provides a new idea to solve the problem of complex system dynamics by combining finite element method and transfer matrix method of multibody system.
