Теоретическое исследование динамической устойчивости цилиндрических тонкостенных оболочек в процессе их вращения при наличии сжимающей нагрузки (линейное приближение)

Abstract

It is shown that the stability of process two-cylindrical of the hardening melt on elastic barrels and the quality of getting ribbons depends on the dynamic stability of circular cylindrical thinness casings The linear problem of dynamic stability thinness casing in the process its rotation and the availability of compressible loading is solved. The analytical expression for the calculation of hollow casing is obtained. The analysis of process oscilation revolving thinness casing is performed. It is determined that the phenomenon of resonance disappears when the coefficient damping δ≥ωo/√2, but the unlinearance of process introduces essential changes in the character oscillations.
