Analysis in Formability of Cylindrical Micro Cup Drawing and Blank Optimization
, 2013 本文係探討微小圓杯引伸成形與料片最佳化之模擬分析。為了驗證有限元素方法能有效分析微小圓杯引伸成形，本文首先模擬微小圓杯引伸凸緣，並與期刊論文之實驗比較，其結果一致。其次，模擬微小圓杯引伸貫穿，分析成形負荷、厚度變化及成形杯高，藉由期刊論文之實驗比較，探討模擬分析與實驗結果之差異。此外，本文為改善金屬板材異向性所導致微小圓杯引伸貫穿之耳緣現象，採用真應變法(true strain method)預測無耳緣之最佳化料片輪廓。本文結果顯示，使用有限元素方法模擬分析微小圓杯引伸成形應屬可行 ...
