Stress-strain state of the lower traverse of the hydraulic press
Journal Title: Журнал інженерних наук - Year 2018, Vol 5, Issue 1
Abstract
In the present article the stress-strain state of the lower traverse of the central ejector of the hydraulic press for manufacturing large-sized plastic products has been investigated by using finite element analysis. It has been established that the stress-strain state of the traverse is characterized by a general and local uneven distribution of stresses and deformations; normal stresses in the cross section, passing through the plane of symmetry of the traverse, change linearly. Various changes of the equivalent stresses along the height on the inner surfaces of the central and lateral cylinders have been established. The zones of the traverse that are experiencing the highest values of normal and tangential stresses and strains have been identified. The research allowed to change the geometry of the traverse with a slight change in the stress and strain and therefore to reduce the weight of the traverse. This investigation and its results will have practical application in the design of new hydraulic presses as well as in improvement of existing hydraulic presses and are also the basis for further research.
