碩士 === 國立臺灣科技大學 === 機械工程系 === 103 === This paper provides a simple but robust algorithm, the Advanced Unconstrained Multicriterion Topology Optimization method (AUMTO), which can obtain the minimum-compliance optimal structure that simultaneously meets the additional stress and/or displacement limits. This innovative unconstrained multicriterion function approach can expand the searching domain to increase the probability of getting the global optimum, reduce the computation time, and be robust to the variations of different initial design selections. The robustness, simplicity and high efficiency of the AUMTO algorithm are fully demonstrated by the three illustrative problems including two cantilever beams and one L-shaped cantilever beam.
