Оптимізація конструкції адаптера касетного підшипникового вузла

Abstract

Finite element method was taken as the main method of research. At the first stage mathematical model included adapter, double row outer ring, tapered rollers, two inner rings and wheel set axle. At the second stage, the features of the influence of the adapter design on the load distribution in the bearing assembly were investigated. The authors have developed a complex multi-contact finite element model for analyzing the stress-strain state, strength and durability of the tapered "cassette" for the 1520 track space. The main regularities of the stress-strain state and the optimal design of the adapter have been found.
