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
等应变模变薄拉延时的上限法研究
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。
