On the Behaviour of Elastic Elements Belonging to the Elastic Tram Wheel at Particular Loading

摘要

The paper proposes an analysis on the influence of the elastic rubber elements as component parts of the elastic tram wheels,as well of the railroad,on the stress state,on the wear and the loss in time of the mechanical properties under dynamic conditions.It is noticed the importance of the proping of the rubber elastic element (all degrees of freedom or vulcanized on a metallic support) going to a "brick" element shape proposal,which is absolutely "covered" for practical applications.This approximation leads to new correction coefficients,as well as to the validation of the simplified "brick" shape of specimens for a future experimental test standartization.
