成形模;
According to the upper-bound theorem, the influence of technological parameters on the average pressure of punch during the ironing with contoured die of equal strain rate is studied.
根据上限原理,研究了等应变模变薄拉延时各变形工艺参数对冲头单位压力的作用。
Meanwhile, with the aid of the minimum energy principle, the optimum height of contoured die ( H0pt), which is an essential variable for ironing with contoured die of equal strain rate, has been calculated.
同时,结合最小能量原理,优化了重要工艺参数&凹模型线高度(H(opt))值。
On ironing with contoured die of equal strain rate by the upper-bound approach
