It is shown that the effective implementation of PLM systems requires a clear classification of heterogeneous information resources and their relationships based on the principles of systems theory, with the involvement of machine learning methods for in-depth analysis and automated classification. Parametric axisymmetric FEA systems for lead screws and threaded connections of sucker rods have been developed and implemented using free software, a multi-agent approach and an actor model. The proposed systems provide modeling of contact interaction, stress-strain analysis and multi-parameter optimization of structures. Geometric modeling is automated based on Cadquery, and the construction and calculation of finite element models are based on Pycalculix, which allows performing a full modeling cycle in automatic mode. An improved multi-agent optimization system, implemented using the Ray package, combines agents with different search strategies, which ensures efficient finding of global minima in multidimensional parameter spaces. Using the developed tools, the influence of structural and technological parameters on stresses in emergency modes was investigated and rational values of thread-cutting tool parameters were substantiated. Directions for further research were formulated, focused on deepening the integration of PLM, modeling methods, machine learning and diagnostic systems in order to achieve a systemic effect of quality and cost management throughout the product life cycle Product Description popup.authors Vitalii G.
