Elastic bodies, undergoing high-speed and large overall motion, may introduce dynamic stiffening due to coupling between rigid motion and elastic deflection. Traditional dynamics can hardly consider these terms. A new kind of element coupling shape function matrices is used in finite element method, so that element elastic displacements is expressed as the second order small quantities of node displacement. The element coupling shape function matrices are derived by means of geometrically nonlinear strain-displacement relation under small deformation assumption. The Kane's equations and the modal coordinate reduction method are used to establish the consistent linearization dynamic equations. A finite element analysis program for spatial truss structures with dynamic stiffening is developed. The validity of the theories and algorithms presented in the paper are verified by a numerical simulation example.
