摘要
利用自行开发的叶片锻造过程三维刚粘塑性有限元模拟系统对单榫头叶片精锻过程进行了模拟分析,揭示了其叶身精锻成形规律,并以塑泥为模拟材料,采用物理模拟的方法对其进行了试验验证。三维有限元数值模拟结果与物理模拟结果的良好吻合表明了单榫头叶片精锻过程三维数值模拟结果的可靠性。该研究对叶片精锻过程的预成形毛坯的优化设计具有重要的指导意义。
The forging process of blade with a tenon is simulated and analyzed by using a 3-D FEM code developed in order to obtain forming laws in the precision forging process of blade. Physical modeling validates the results of numerical simulation using plasticine as modeling material. A good agreement of numerical simulation results and physical modeling results shows that the results of the numerical simulation are reliable in the forging process of blade with a tenon. This study is important to optimum design of the billet in the precision forging process of blade.
