Abstract
The analysis of effects of emergence of critical states of rigid and elastic thin-wall conical shell frustums hinged or elastically attached by their smaller edges to a rotating platform is performed on the basis of hybrid differential equations. The cases of simple and compound rotations of the carrying platform are considered. It is established that in the case of simple rotation the peculiarities of the critical state onset for the rigid and elastic shells are determined by relationships between their axial inertia moments, whereas in compound rotation the first frequencies of precession resonant vibrations of elastic shells do not depend on elastic pliability of the ties between the shell and the platform.
