UNDER THE THERMAL ACTION ON THE CABLE

Longitudinal oscillations of an orbital cable system 
(OCS) composed of two end masses and a connecting cable are considered. 
The change in the temperature of the cable in orbital motion is responsible 
for the disturbing action. It is evident from the analysis of the 
natural frequencies of the OCS longitudinal oscillations that the 
fundamental tone can coincide with one of the disturbance harmonics. 
In the conservative dynamic model of an OCS, the complete attenuation 
of the cable is attained at resonance in several circuits of the orbit.
