摘要
冷弯成型变形复杂,事先难以预测其变形效果。根据冷弯成型的特点和变形规律设计出基于万能实验机上的局部大变形测试装置,并应用此装置对冷弯成型过程进行回弹分析,为冷弯成型理论分析和使用ANSYS/LS-DYNA对冷弯成型分析提供科学依据。
Cold roll forming is a process with complex distortion and hardly estimate in advance, Based on characters of roll forming process, springback analysis and material mechanic machines, testing devices of local large deformation were designed. The study of these devices provides proofs for theoretic analysis and ANSYS/LS- DYNA simulation of cold forming process.
