提出了一种新型W钢带成型工艺并利用西门子S7-200 PLC设计出W钢带机自动切断冲孔控制系统。利用非线性有限元Marc对W钢带成型进行建模仿真,得到弯角处的等效塑性应变等力学性能,验证了工艺的合理性。
Proposed a new type of W strip forming process and the use of Siemens S7-200 PLC designed W strip machine automatic cutting punching control system. The non-linear finite element Marc was used to simulate the forming of W steel strip. The mechanical properties such as the equivalent plastic strain at the corner were obtained, which proves the rationality of the process.
