The Study of Strength and Stiffness of the Vulcanized Machine's Cross Member
Wei hua
ABSTRACT
In this paper, by using the combined method of numerical
calculation and the model test, analysis of strength and
stiffness in the cross member of vulcanized machine which
is recently designed by Shen Yang Rubber Machine Factory
under critical conditions are performed in detail.
In the course of using vulcanized machine, it is an
outstanding problem that tires come into being useless
edge, urgently requires resonable calculated method to
guide design and production, This paper is center on this
problem. By using FEA software ALGOR analyzes strength and
stiffness of the cross member under many kinds of forms,
and using model test to test and verify the calculated
results of finite element. By means of analyzing the
results of calculation and experiment, we obtain a result
that the strength and stiffness of cross member is
reasonable.
As the same time, from the analyzing and comparing of
diverses schemes we get a conclusion: it is more resonable
by using membrane element than plate element to analyze
the cross member by using finite element.
This paper solve the practical engineering problem, and
search for a way of numerical calculation and experiment
to solve the problem. At present, reference about this
direction is little, domestic study is especia1ly little.
Therefore, we not only solve the practical engineering
problem, gain economic benefits, but also provide valuable
reference for researching the similar problem in the future.
