Abstract
The paper considers some peculiarities of the operating conditions of longwheelbase flatcars. It is analyzed the main reasons for the failure of elastomeric draft gears. The most rational ways to reduce the load on long-wheelbase flatcars are proposed and justified. An analysis of changes in ambient temperature during the passage of container trains from the Central part of Russia to the Republic of Sakha (Yakutia) was carried out, and ways to ensure trouble-free operation of elastomer and rubber-metal draft gears were proposed. A computational model is proposed to study the operation of sequentially located (double) draft gears. The necessity of using computer modeling methods to test the effectiveness of the proposed arrangement of draft gears is substantiated.
