- Abstract
In order to explore the influence mechanism of micropores on the stress concentration of 2219 aluminum alloy welds,2219 aluminum alloy was selected as the research object in this paper, and establishes the finite element model of single hole and double hole based on ANSYS finite element analysis software. The influence of the size, position and shape of the single hole and the double hole on the stress concentration of the weld. The finite element simulation results show that the stress concentration direction of a single hole is always the same as the short axis direction of the ellipse, and the maximum stress and the hole radius show a significant positive correlation between the maximum stress of the weld and the distance between the hole and the weld center And the maximum stress between the maximum stress in the X-direction of the double-hole and the width of the ligament is positively correlated and linearly related. The maximum stress and the ligament width in the Y-direction show a tendency to decrease first and then stabilize. Characteristics, the greater the width of the ligament, the greater the greater the stress.
