摘要: 介紹三維曲面柔性卷板成形技術,并與傳統卷板成形和多點成形進行了對比.對柔性卷板成形裝置進行研究并開發出相應的實驗裝置.建立柔性卷板成形的有限元模型,并對其成形過程進行數值模擬,得到了較好的模擬結果.模擬了兩種不同材料板材的成形效果,分析了其產生不同成形效果的原因.Abstract: Three-dimensional surface flexible roll bending was introduced and compared with traditional roll bending and multipoint forming. The flexible roll bending equipment was researched and the corresponding experimental equipment was developed. A finite element model of flexible roll bending was established to simulate the forming process and satisfactory simulated results were gained. The flexible roll bending of sheet metals made of two kinds of materials was simulated and their different forming effects were analyzed.
