INFLUENCE OF HYDRAULIC PRESS COLUMNS CONNECTION ON DYNAMIC PROPERTIES

Abstract

This paper deals with possibilities of hydraulic press design optimization. Dynamical loading is deeply discussed here. Technological operation called high speed forging is often used on this kind of machines. This technology leads to vibrations of whole hydraulic press. It must be ensured, that the lowest natural frequency of the whole press is higher comparing with frequency of forging. In research was performed finite element analysis, which showed influence of design modifications.
