摘要: The design of a bistable mechanism with a specified resonant frequency by an optimization approach is presented. This optimization approach combines finite element analyses and a genetic algorithm. Quick design of a compliant bistable mechanism with a specified resonant frequency is achieved. A prototype of the designed device is fabricated. The experimental results confirm that the prototype has bistability and the specified resonance frequency.
本文利用一個最佳化基因演算法的設計方式,設計出一個具有特定共振頻率的雙穩態能量擷取器。所提出的整合有限元素分析與基因演算法的最佳化設計方式,能有效的設計與分析可撓性雙穩態機構,使其具有趨近於所指定之共振頻率。使用工程塑膠材料製作一個可撓性雙穩態機構模型,實驗結果與設計標的相符。
