Finite Element Analysis for the Resistance Spot Welded Impeller of the Centrifugal Pump
摘要
Abstract
To accurately calculate the stress and deformation of the resistance spot welded impeller in the flow field, the finite analysis for the impeller was carried out by means of the CAE co-simulation platform used for the multi-physical fields------ANSYS Workbench, with one-way fluid structure interaction method. Firstly, the sensitivity of the finite element analysis models of the impeller on different mesh density was analyzed. Then, the equivalent ( von-Mises) stress and total deformation of the impeller at the design flow rate condition were calculated. Moreover the characteristic of the maximum stress and total deformation at different flow rates was investigated. The results provide effective references to the structural design and optimization for the resistance spot welded impeller.关键词
