Об одном подходе к исследованию статики и динамики комбинированных систем оболочек вращения

Abstract

A peculiar method for computing static and dynamic state of com-bined shell structures is discussed, as well as the relevant algorithms and some specific ex-amples. The proposed digital procedure, as compared to the known ones, is of the enhanced accuracy and processing speed, higher reliability and lower hardware requirements. It does not demand high professionalism from a user in reprocessing phase, and never-theless, is of a rather broad applicability. The non-linear differential equations of dynamics of shell of revolution were the mathematic model and the basis to formulate the equations for calculating the unperturbed static and dynamic state, as well as the equations in dis-turbances for computing the problems of small-ampliude oscillation, stability and bearing ca-pacity. The numerical algorithm is based on relatively simple recurrent processes and on a number of specially created program units, that ensure the features noted above.
