摘要: 為了解決分段多點成形過程中的技術難題,利用數值模擬軟件對其成形過程進行數值模擬.以顯式算法模擬加載成形過程,隱式算法模擬卸載回彈過程,從而實現分段多點成形的數值模擬.采用非均勻有理B(NURBS)樣條曲線設計過渡區形狀,探討了過渡區大小對成形品質的影響.結果表明,在合理設計過渡區的情況下,分段成形品質好于一次成形.

Abstract: In order to resolve technique problems in sectional multi-point forming, the forming process was simulated by a finite element software, in which dynamic-explicit formulation was used to analyze the loading processes and implicit algorithm formulation for the unloading processes. The forming surface of transition area was designed by non-uniform rational B-surface (NURBS), and the width of transition area that has effect on the quality of sectional forming parts was discussed. It is shown that when simulated with an appropriate design of transition area, sectional forming parts possess a better quality than one-step forming parts.
