James, Kai A Kelley, Patrick Louis 2021-09-17T01:13:31Z 2021-09-17T01:13:31Z 2021-04-28 2021-05 Several wheel-barrow mechanisms were synthesized from first principles using a topology optimization method. First, a shape optimization problem was formulated in order to generate a wheel geometry that minimizes work done while rolling over terrain. Flat and sinusoidal ground profiles were considered, resulting in approximations to a circle and ellipse, respectively, as expected by an analytical solution. These optimal shapes then supplied a slate of contact points for a multi-load multi-layer mass minimization problem, subject to compliance constraints, which created a wheel-barrow system. Finally, the shape and topology regimes were optimized simultaneously, in an integrated multidisciplinary design optimization (MDO) framework. In all cases, analytically-derived sensitivities were supplied to the Method of Moving Asymptotes (MMA) optimizer routine. Submission original under an indefinite embargo labeled 'Open Access'.
