Модель основана на уравнениях теплового баланса и кинетики износа, учитывающих диссипацию энергии при трении и теплообмен с окружающей средой. В отличие от традиционных подходов, предложенная модель включает в себя критические точки, соответствующие температурным переходам в полимере, что позволяет прогнозировать их положение на экспериментальных зависимостях с высокой точностью. Особое внимание уделено деструкции свойств полимера под воздействием температуры и механических нагрузок, существенно влияющей на трибологические характеристики пары трения. Модель реализована в САПР MatLab с использованием метода конечных элементов для численного решения уравнений теплопроводности и износа. Результаты моделирования, сопоставленные с экспериментальными данными, демонстрируют адекватность модели и возможность ее применения для оптимизации параметров трибологических систем „сталь–полимер“.</p></abstract><trans-abstract xml:lang="en"><p>A mathematical model of wear of a steel–polymer friction pair without lubrication is proposed. The model is based on the equations of thermal balance and wear kinetics, which take into account energy dissipation during friction and heat exchange with the environment. Unlike traditional approaches, the proposed model includes critical points corresponding to temperature transitions in the polymer, which makes it possible to predict their position based on experimental dependences with high accuracy. Special attention is paid to the destruction of polymer properties under the influence of temperature and mechanical loads, which significantly affects the tribological characteristics of the friction pair. The model is implemented in MATLAB CAD using the finite element method for the numerical solution of the equations of thermal conductivity and wear. The simulation results, compared with experimental data, demonstrate the adequacy of the model and the possibility of its application to optimize the parameters of tribological systems steel–polymer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>MatLab</kwd><kwd>трение</kwd><kwd>износ</kwd><kwd>легированная сталь</kwd><kwd>полимер</kwd><kwd>температура в зоне контакта</kwd><kwd>коэффициент трения</kwd><kwd>коэффициент износа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>MATLAB</kwd><kwd>friction</kwd><kwd>wear</kwd><kwd>alloy steel</kwd><kwd>polymer</kwd><kwd>contact temperature</kwd><kwd>coefficient of friction</kwd><kwd>coefficient of wear</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации (тема № 124041500009-8).</funding-statement><funding-statement xml:lang="en">The work was performed within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation (topic No. 124041500009-8).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Armstrong-Hélouvry B., Dupont P., &amp; Canudas de Wit C.
