Abstract: | A mechanical system consisting of a spacecraft with weightless elastic tether and load is considered in the paper. The spacecraft
motion under the action of tensile force of a radially oriented tether is investigated. It is shown that elastic tether oscillations
can result in appearance of chaotic modes of spacecraft motion. By means of the Melnikov method a condition is obtained, allowing
one to determine the measure of damping sufficient for prevention of these chaotic modes. The influence of system’s mass-geometric
and elastic characteristics on the form of phase portrait and on the value of periodic disturbance, caused by oscillations
of the elastic vertical tether, is studied. |
