Сайлентблоки являются важной составной частью систем подрессоривания современных автотранспортных средств. Их свойства определяют не только комфортность передвижения на автомобиле, но и оказывают влияние на упругую характеристику подвески. При деформации сайлентблока в его силовой характеристике возможно появление линейных участков, которые целесообразно описывать с использованием математической модели, построенной на основе классических элементов Гука и Сен-Венана.

Rubber bushings are important parts of the spring systems of modern vehicles. The properties determine not only the comfort of car movement, but also affect the elastic suspension characteristics. When a bushing is deformed, linear sections appear in characteristics. It is advisable to describe such characteristics using a mathematical model based on the classical elements of Hooke and Saint-Venant. The paper presents a mathematical description of the bushing simulation functioning results, accuracy of approach, areas of application of the mathematical model.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The initial data was the experimental characteristic of a cylindrical automobile rubber bushing, obtained in harmonic mode at the 0.03 to 51 Hz frequency and the 0.4 to 10 mm amplitude. The force balance of the two Hooke elements and one Saint-Venant element interacting with each other determined the mathematical model description. The authors carried out the calculations using numerical and optimization methods.</p></sec><sec><title>Results</title><p>Results. As a result, the authors determined functions characterizing the change in the parameters of the Hooke and Saint-Venant elements from the rubber bushings’ deformation amplitude. Moreover, the authors calculated power characteristics in the form of dependences of the rubber bushing effort and also found quantitative indicators of the reliability of the experimental data approximation by the developed mathematical model.</p><p>Discussion and conclusions. The analysis of the operating modes shows the possibility of the model application to describe the rubber bushing functioning in a stationary harmonic mode with small and medium strain amplitudes. The simulation results of the Hooke’s and Saint-Venant’s parameters reveals the theoretical prerequisites for the possibility of using the model to calculate the bushing force in an unsteady mode.</p><p>The authors have read and approved the final manuscript. Financial transparency: the authors have no financial interest in the presented materials or methods. There is no conflict of interest.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>система подрессоривания автомобиля</kwd><kwd>резинометаллический шарнир</kwd><kwd>модель тела Гука</kwd><kwd>модель тела Сен-Венана</kwd><kwd>математическое моделирование</kwd><kwd>амплитуда</kwd><kwd>частота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>car suspension</kwd><kwd>rubber bushing</kwd><kwd>Hooke element</kwd><kwd>Saint-Venant element</kwd><kwd>mathematical modeling</kwd><kwd>amplitude</kwd><kwd>frequency</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Выражаем искреннюю благодарность руководству Восточно-Сибирского государственного университета технологий и управления в лице ректора д-ра экон. наук, проф.
