摘　　要：利用刚粘塑性有限元法,对某重型燃机压气机叶片的多工步锻造过程进行了三维有限元模拟。通过有限元数值模拟,得到了多工步锻造过程中坯料的几何形状变化、温度场和应变场的分布规律以及载荷变化曲线。模拟工艺实验表明,压气机叶片锻造工艺和模具设计合理,数值模拟结果准确可靠。Using 3-D rigid-viscoplastic finite element method, the multi-stage forging process of a gas turbine compressor blade was simulated. Through the simulation, the deformed geometries of billet, the distributions of temperature and strain, and the forging load have been obtained. The results of practical tests showed that the technical design of multi-stage forging of compressor blade is reasonable, the die cavity design is accurate and the numerical-simulation is effective. The study is of significance to the engineering application of multi-stage forging of gas turbine compressor blades.
