We propose a new approach to the mathematical description of the dynamics of a large space structure as a deformable body. The concept of kinematic parameters as applied to the motion of deformable body is proposed. The finite velocity of the propagation of mechanical interaction is taken into account. The three-dimensional model of dynamics is substituted by equivalent four-dimensional model of statics, and the equilibrium equations of forces and torques are given for the latter model.
