MODELING OF A SPRING-FRICTION ENERGY-ABSORBING DEVICE FOR A FREIGHT CAR
Abstract
Energy-absorbing devices are designed to dissipate impact energy, thereby
reducing the longitudinal tensile and compressive forces transmitted to the wagon frame
through the coupler. In operational practice, the most common units are hexagonal
spring-friction devices of types Sh-1-TM, Sh-2-V, Sh-6-TO-4 and others because of their
simplicity and the possibility of designing them with satisfactory parameters.
