FEM ANALYSIS OF GEROTOR MACHINES IMPELLER WITH PLANETARY MOTION

Abstract

This paper presents the finite element method analysis in a gerotor machine impeller. The analysis was carried out for the impeller of a gerotor machine with planetary motion. So far, a lot of has been conducted on the topic of the gerotor machines with the fixed position of the axis of the impeller element, while in the case of planetary motion of the impeller there are much less researchings. This case requires a more complicated force analysis, which is necessary for setting constraints and loads in finite element analysis. The mathematical model of the gerotor impeller force analysis with planetary motion is taken from the literature. The paper analyzes for cases with several combinations of teeth numbers with variation of materials. At the end of the paper, the results obtained by this analysis with conclusions and given further directions of research on this topic were presented.
