SIMULATION-BASED NONLINEAR PRESTRESSED MODAL ANALYSIS OF A STRUCTURE (IMPELLER PUMP) USING ANSYS

Abstract

Impeller-type pumps are widely used in fluid-handling systems where structural stiffness and
elastic integrity under operational loading are critical. This study presents a linear static structural
analysis of a five-component impeller pump assembly subjected to a 100 N belt-equivalent bearing
load. The objectives are to verify that impeller deflection remains below the allowable limit of
0.075 mm and to ensure that the Polyethylene pump housing operates within its elastic limit,
particularly near the shaft bore where stress concentration is expected.
