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 the design process of the leaf blade preform structure, the final forging process simulation was performed on the blade body with different pre-bent blade forms and different torsion angles by using Deform-2D finite element analysis software. Through the comparison of the formability, the deformation uniformity, the heat loss of the blank before forming, and other key factors, the influence of different preform leaf structure on the forming and quality of the final forging was analyzed in detail. On this basis, the traditional structure was optimized Finally, the ideal model of pre-deflated blade structure was obtained.
