- W4328126633 abstract "Purpose: To study the job of polymer elements of coupler draft gear. To develop the models of polymer elements of draft gear retaining set given the use in a polymer element of parts that lose stability during an operation. To obtain force characteristics of the developed models of polymer elements with the help of computer simulation. To compare the parameters of obtained force characteristics with the experimental data of non-modernized polymer element. As an object of research, to use supporting polymer element of draft gear PMKP-110. Methods: Computer modeling based on finite element method (FEM) was used to determine optimal variant of polymer element geometry. Since polymer elements’ job involves significant deformation of the elements themselves, the simulation was carried out in software package, which specializes in solving highly nonlinear problems. To compare the effectiveness of the developed models, the polymer element experimental study was carried out. Results: The necessity to study and modernize polymeric suites of automatic coupler draft gears is shown. One of the directions for polymer elements modernization is considered and several variants for polymer element models designed within the studied trends are presented. The most promising variants from possible models was chosen. Further research recommendations are given. Practical significance: The considered approach in polymer element study and modernization makes it possible to obtain a polymer suite with force characteristic improved parameters – an energy intensity and completeness coefficients. Such polymer suites installed into draft gears can increase their reliability, increase the efficiency that in a whole can affect the safety of cars and goods they carry." @default.
