Вынужденные колебания венца рабочих лопаток турбомашин с учетом демпфирования

Abstract

The problem of turbine engines bladed disks forced vibration has been studied; the internal and constructional damping has also been considered. The new mathematical model that gives an opportunity to take blade’s structural inhomogeneity into consideration has been developed by means of finite elements method. The results of the turbine bladed disk vibration amplitudes, forced by variable aerodynamic force are attached
