摘要
利用计算机数值模拟软件DEFORM2D，对厚钢小孔冲裁（t〉4，d／t≤1）过程进行模拟与分析，得出了其断裂与变形机理。通过DEFORM3D进一步优化成形参数，得出了间隙对厚钢板小孔冲裁力的影响规律，为提高厚钢板小孔冲裁模的寿命提供了理论依据。
Process of small hole punching on thick steel plate （t〉4, d/t≤1 ） is simulated and analyzed by Deform 2D. Forming and crack mechanism are obtained, Optimization of forming parameters has been offered to get the influencing rule of tolerance on punching load by Deform 3D. Theoretical basis for increasing life span of small hole punching on thick steel plate may be acquired.
