Influencing dynamic loading on the characteristics of polymer shock absorbers

The article is devoted to studying the influence of dynamic loading on the polymer element characteristics of rolling stock shock absorbers and to the description to creating a mathematical model of their work. The results of mathematical modeling are further used to solve problems of the rolling stock longitudinal dynamics. While studying, the initial loading rate varied, the room temperature and the effect of the wear factor remained unchanged. For the operating speeds of a freight car movement, a mathematical model of RMCP (rectangular, metal-ceramic, polymer) -110 draft gear was determined.
