【 摘 要 】

This paper describes the principles of the computerized system for creating geometric models of threaded joints with various geometric deviations, which arise during the thread turning, and demonstrates the use of these models to determine the dependencies of reliability indicators on these deviations by the finite element method. Using the developed system, based on Python and FreeCAD, axisymmetric finite element models of drilling tool joints and sucker rod couplings with deviations of the profile angle and the thread pitch were created and analyzed.
