Determination of Conditions of Technical Stability of Dynamic States of Moving Continuous Systems Interacting with Liquid Flow

摘要

The approach to investigation of the nonlinear multidimensional dynamic processes of the interaction with the liquid flow of the moving extended continuos systems on the basis of the nonlinear space elastic theory together with the method of comparison and with the Lyapunov second method is developed. The different general systems of the nonlinear equations of motion of the given continuous processes are obtained on this basis. Conditions of technical stability of nonlinear boundary value problem which helps to characterize the dynamic behaviour of the investigated systems moving in liquid flow are indicated.
