Development of a Load-Agnostic Structural Light-Weighting Design Optimization Methodology

Abstract

A proof of concept modeling and simulation strategy has been demonstrated, identifying sizable weight save opportunities based on load-agnostic optimization methodology. The chosen design upon topology optimization yielded 15 percent weight, exceeded targets for stiffness (+10 percent avg) and strength (+32 percent avg) and first three natural frequencies (+16 percent avg). In an independent study, a Senior Capstone project at University of Michigan, Ann Arbor, realized a 17.5 percent weight savings in the same component, but by employing known service loads.
