Payload is a key performance measure for military vehicles, determining how many personnel and/or goods can be carried. Reflecting this, the US Army Ground Vehicle Systems Center (GVSC) is engaged in a project to reduce the curb weight of vehicles, and thereby boost payloads, by redesigning and replacing existing components with lighter alternatives. Specifically, GVSC is combining topology optimization with additive manufacturing to realize significant weight savings, without compromising other critical requirements. Altair was contracted for external expertise to create new component designs. The results included achievement of 67% mass reduction for an alternator bracket, and cheaper costs than the current machined baseline.
