| Abstract: | Correct understanding of the dynamic stiffening problem is signality for further researching spacecraft dynamics and establishing a rational numerical model of flexible body dynamics.The dynamic stiffening problem was studied using the theory of a mechanical problem in a non-inertial coordinate system.Two kinds of numerical models for the dynamic stiffening problem were established.The physical meaning of the dynamic stiffening problem was clarified.The approach of correct zero-order modeling was explored.There is a substantive difference between the research of this paper and the research of other scholars. |
