Розрахунок нестаціонарних процесів в електромеханічних системах бурових установок

Abstract

On the example of the lifting system of drilling rigs the method of calculation of nonstationary processes in machine units is offered, which is based on joint integration of nonlinear differential equations of electromagnetic state of induction motors and usual differential equations and partial differential equations describing the motion of mechanical system. in the elements of machines and makes it possible to detect self-oscillating phenomena of quasi-resonant nature and predict the life of critical parts and components. To numerically implement the method, an algorithm for solving problems using finite-difference sampling of units with pronounced distributed parameters is constructed.
