本文採用材料分佈法以最小化結構應變能對相互位能的比值，以正常化材料密度為設計變數時，採用逐次線性規劃法以求得二維的最佳撓性放大結構拓樸形狀。本文模擬Uchino的印字頭放大機構作動方式，以本文所述之撓性放大結構拓樸設計方法，重新設計二維的放大器結構，在受靜力的條件下顯現良好結果，研究將繼續延伸至動態力無阻尼的狀況。 Material density is design variable and material distribution method has been used for minimizing the structural strain energy as well as maximizing the mutual potential energy in topology optimization. Sequential linear programming has been adopted in design a displacement-amplifying mechanism for simulating the piezoelectric stacked actuators of a printer head. The design concept and the formulation are given and explained in the paper. The optimal results appear that the desired output location of the design domain has an obvious displacement. The future study will extend to dynamic input with undamped or damped circumstances.
