Structural optimization of a metal sheet with hole
Summary • Model definition and Parameterization • Structural analysis • Optimization workflow • Analysis of results
Model Definition • The model is a metal sheet with hole. • The sheet is fixed constrained along the bottom edge • Two distributed loads along top and right sides are applied
Model Parameterization Model parameters are: •
Position, dimension and fillet of the hole
•
Thickness of the metal sheet
Structural Analysis
• The mesh is automatically created by Workbench • The distributed loads are applied on two side surfaces (100 N)
Optimization Workflow (modeFRONTIER)
Design Parameters
Optimization’s set-up data
Input variables • 5 geometric variables
Sampling phase: • Original configuration – nr initial individuals: 16
Output variables • Maximum stress and displacement • Mass
Design goals • Minimize maximum displacement • Minimize mass
• The Parallel Chart allows the filter of the designs in order to get the optimal values for both the objectives • The set of Best Designs (Pareto frontier) can be visualized
Optimization Analysis – Correlation Chart
• Displacement is inversely correlated with mass • Displacement is inversely proportional to thickness • Mass is directly proportional to thickness
Optimization Analysis – Bubble Chart 1
• The Bubble plot shown is a 4D view of the scatter • It compares the design that have been investigated with respect to different objectives
