高深寬比金屬板材微流道之液壓成形研究

Abstract

本研究透過本實驗室之靜水壓成形機台進行實驗，使用厚度為0.1mm之SUS304薄板，分別施加5種不同的壓力，成功地將微流道壓印在板材上，得到高深寬比之微流道。同時利用有限元素模擬軟體Abaqus/Standard針對金屬板材微流道之液壓成形做有限元素分析，將材料試驗所得到不□鋼板之材料參數、模具幾何外形與邊界條件等來建立有限元素模型，比較此模擬結果與實驗之成形性來進行驗證。藉此有限元素模型，利用最佳化軟體SmartDo串聯有限元素軟體Abaqus/Standard，調整模具的幾何形狀、成形壓力等，以液壓成形來完成微流道流道深寬比的最佳化以及氣體反應效率的最佳化，並將其最佳化結果與實驗、相關文獻作比較與討論。

This research had experimented by using the novel hydroforming machine. Using five pressure to print microchannels on SUS304 Stainless Steel Sheet, the thickness is 0.01mm.To obtain microchannels with high aspect-ratio.Simultaneously, using Abaqus/Standard to analyze the microchannels on metallic sheets hydroforming process. The material properties were first obtained through uniaxial tensile tests, then the finite element model were built. And the deepest channel height is taken as the indicate of sheet’s formability .By the difference of the formability. this research compared the results of simulation and hydroforming experiment for verifying the accuracy of the finite element model.Finally, to finish the optimization for aspect-ratio and optimization for reaction efficiency with hydroforming by changing the various dimension of flow channel and pressure.
