英文文献1《大型自由锻开坯工艺的数值模拟和物理模拟分析》

石楼闲睡

最近读的一些文献都是用模拟软件研究大型自由锻的中心压实问题的。
我传几篇比较有代表性的，现在模拟软件在米国很流行，不少厂家请高校在做（或者自己做）。模拟软件不可能成为这个行业的主流、无论是软件开发还是计算机升级都要慢慢来~但我觉得咱们可以师夷长技以制夷~

废话到此结束。

摘要：For a design of the cogging processes to obtain sound forgings of the monoblock rotor, the effects of forging parameters have been investigated. Parameters such as die configuration, die width and reduction of height have been considered in the designed of the process. The three-dimensional finite element analysis is carried out for the cogging process in order to study the distribution of effective strains, hydrostatic stresses and axial stresses. Physical modelling of 1/40th scale using plasticine modelling clay is performed to verify the results of simulation and to design the process. Optimal working conditions of heavy ingots are suggested for defect-free product quality.
