- Аннотация: The paper develops an approximate solution by means of an averaging method to the system of Euler's equations with additional perturbation terms for a nearly dynamically spherical rigid body containing a viscoelastic element. The averaging method is used. The asymptotic approach permits to obtain some qualitative results and to describe evolution of angular motion using simplified averaged equations and numerical solution. The main objective of this paper is to extend the previous results for the problem of motion about a center of mass of a rigid body under the influence of small internal torque (cavity filled with a fluid of high viscosity) or external torques (resistive medium, constant body-fixed torque). This paper can be considered as mainstreaming of previous works. The advantage of this paper is in receiving the original asymptotic and numerical calculations, as well as solutions that describe the evolution of motion a rigid body with a moving mass over an infinite time interval with an asymptotically small error. The paper presents a contribution in several areas, partially in the problems of spacecraft and satellite motion, and the activities of crew members about the vehicles. The importance of the results is in the progress of moving mass control, and in the motion of spinning projectiles.
