摘要：

在叶片叶身预锻结构形式的设计过程中，利用Deform-2D有限元分析软件对不同预锻叶身形式、不同扭角位置处的叶身进行了终锻过程模拟。通过比较成形性、变形均匀性、成形前毛坯的热损失等关键因素，详细分析了不同预锻叶身结构对终锻件的成形及质量的影响，并在此基础上，对传统结构进行优化设计，最终获得了较理想的预锻叶身结构模型。

During pre-forging shape design of blade body, the final forging process including different pre-forging forms and transverse cross positions of different twist angles along blade body were simulated by using Deform-2D finite element analysis software. The final forging forming and quality effected by different pre-forging shapes of blade body were analyzed in details through comparing some key factors such as formability, deformation uniformity, loss of heat before deformation, etc. Then, based on traditional model, improved shape was designed and optimal pre-forging shape of blade body was obtained finally.
