Application of the Parallelized Topology Optimization for the Dynamic Characteristics Improvement of a DVD Pickup Bobbin

DVD 픽업보빈의 동특성 개선을 위한 병렬위상 최적설계법 응용

A parallelized topology optimization is applied to the design of a DVD-pickup bobbin, for which the design objective is to maximize the fundamental frequency within a given mass limit. Unlike the existing serial topology optimization, the present method can deal with a large number of design variables, and thus can yield practical and realistic results. The structural member-sizing filter is also employed to control the topological complexity of the optimized bobbin structure.
