Computer modelling of drill string of an oilwell drilling rig

2018 14th International Conference on Advanced Trends in Radioelecrtronics, Telecommunications and Computer Engineering (TCSET), 2018
The article considers the questions of construction and computer realization of the mathematical model of drill string of a drilling rig. An approximation model is proposed in the form of systems of ordinary differential equations. Built on their basis, the computer model of the drill string has several important properties: allows you to reproduce the
