Abstract

The theoretical aspects of dynamic structural analysis are considered and a numerical example is analyzed for the high pressure gear pump housing. The structural model is based on 3D elements.

The software package COSMOS is applied. The obtained results, based on the fundamental level of the housing structural dynamic behaviour with real boundary condition, refer to eigen frequencies and eigen modes of oscillations, that are represented in graphic forms.

Keywords: crack initiation, gear pump housing, dynamic analysis, eigen frequency, eigen modes of oscillation
