In this paper, the finite element analysis of a special form of variable curvature curved beam element is studied and equilibrium equations of variable curvature curved beam element are established in polar coordinates. Based on the principle of energy method, the relationship between nodes displacement and force is obtained and expressed in the form of matrix. By matrix integral operation, the variable curvature curved beam element flexibility matrix is obtained and is expressed in the form of analytic solution. By the element flexibility matrix inversion, the element stiffness matrix is obtained. The research achievement in this paper provides a new a kind of method in the research of finite element analysis of variable curvature curved beam. The finite element calculation of constant curvature curve beam is only a special case of the calculation method in this paper.
