中文摘要 | 孔型輥軋加工是一個複雜的、三維的、塑性成形問題,在實際的製程中有很多個製程參數,為了獲得較佳的工件品質,工程師需慎選各個製程參數值。本文使用複合數值解析模式進行解析模擬各種孔型輥軋,並配合模擬退火法(Simulated Annealing)來分析孔型輥軋各個製程參數及其最佳組合。以square-to-oval孔型輥軋加工為例,孔型半徑、中心高度減縮比、寬厚比等為重要製程參數,本文可以尋得一組最佳參數組合,該組合所加工之形狀品質與變形所需之消耗功率確實是較佳者,未來將有助於輥軋製程設計工程的分析,以及尋找出所有重要製程參數之最佳組合。 |
英文摘要 | Caliber rolling is a comprehensive 3D metal forming problem. In point of fact, some parameters involve in caliber rolling. The choices of parameters including caliber radius, reduction percentage of central height, the ratio of width to thickness, etc. must be seriously considered for the square-to-oval caliber rolling in order to achieve the best quality of product. In this study, the complex analytical model and simulated annealing method were combined correctly and quickly to reach for the optimal combination of the process parameters in order to achieve the best shape quality and least consumed power required for deformation. Through the optimal parameter combinations, it can reduce the procedures of process design and save the working time with respect to the caliber rolling. |
