Stress Analysis of Perforated Plate Based on ANSYS

Abstract:

Based on nonlinear FEA software ANSYS, 3D simulation models of eighteen-type perforated plate that have different open-pore number was established. Analysis results indicate: Maximum equivalent stress of perforated plate mainly takes place on symmetry center of outer open-pore for open-pore area. With increasing open-pore number, maximum equivalent stress and each-direction maximum stress of perforated plate presents to enlarge trend. When open-pore number less than or equal to twelve, value of maximum equivalent stress mainly is decided by Z-direction maximum stress. When open-pore number greater than twelve, value of maximum equivalent stress mainly is decided by Y-direction maximum stress. When ratio m less than 2, with increasing ratio m, maximum equivalent stress and each-direction maximum stress of perforated plate presents to reduce trend. When X-direction and Y-direction open-pore numbe of perforated plate is basically equilibrium distribution, X -direction maximum stress is about equle to half of maximum equivalent stress.
