本研究使用有限元素法、最佳化設計與拓樸設計的理念,結合結構分析軟體ANSYS於一最佳化設計系統中,以建構拓樸最佳化設計整合系統。在進行完第一階段拓樸最佳化設計後,使用混合法來同時保留及移除必要與非必要元素,接著再進行第二階段拓樸最佳化設計,最後使用Bezier曲線函數之概念定義設計參數上下限來平滑結構外形,經過這三階段拓樸最佳化設計後,可改善原始最佳化設計不連續之現象,以達到更具實用性之拓樸最佳化設計。 A system including finite element analysis software ANSYS, optimization method and topological design was developed in this study. This system provides a user-friendly environment for engineers to execute the multi-stage topology optimization easily. After carries on the first stage to topological optimization design, we use the element growth-removal combined method (EGRCM) simultaneously to grow and remove the essential element and the non-essential element on the second stage. The third stage, new design move limits were obtained by Bezier curve concept to smooth the design shape. After three stages topological optimum design, the primitive design can be improved to more practical topological design.
