【摘要】 精密锻件在工艺设计过程中往往存在多种可供选择的工艺方案, 为了获取最佳的工艺方案, 本文首先建立起工艺评估与优化的数学模型, 然后通过有限元仿真技术对各种工艺方案进行模拟, 获取应力、应变、载荷等工艺评估与优化模型所需要的相关工艺参数。通过两种技术的结合应用, 不仅可以在较短的时间内对锻件的最佳工艺方案做出选择, 而且可以大大减少工艺开发过程的试模成本。更多还原

【Abstract】 During forging parts’ process design, there usually exist several process routes which can be chosen. In order to get the best process route, first, mathematical models for process evaluation and optimization are set up respectively. Then finite element simulation technology is adopted to simulate all process sequences. The aim is to get those process parameters that the former mathematical models needed, such as stress, strain, and load. Through the combination of those two techniques, the best process route can be acquired quickly. What’s more, the cost for moulds’ trials can be cut down sharply also.更多还原
