摘要：

针对航空框梁构件等温局部锻造过渡区材料跨变形区转移而导致折叠缺陷的问题，基于Deform有限元模拟与正交试验相结合的方法，研究了变形速度、摩擦因数、变形温度及过渡区坯料厚度分配对于材料跨变形区转移的影响规律及影响的显著性。结果表明：摩擦因数和坯料体积分配对材料转移的影响较大，而变形速度和变形温度对材料转移几乎没有影响；较大的摩擦因数和较少的坯料体积分配，可减少材料跨变形区转移量，降低折叠风险。通过选取较优的模拟方案进行分析与对比，发现过渡区材料转移量明显减少，避免了过渡区折叠缺陷的产生。

For the problem of folding defect caused by the trans-regional material transfer in the transitional zone of the isothermal local loading forging of aviation frame beam components, and base on the combined method of finite element simulation by Deform-3D and orthogonal test, the influence laws and significance of deformation speed, friction factor, deformation temperature and billet thickness distribution in transitional zone on material transfer were investigated. The results show that the friction factor and the billet volume distribution have a great effect on the material transfer, while the deformation speed and the deformation temperature have little effect on the material transfer. Furthermore, a larger friction factor and a smaller billet volume distribution can reduce the amount of trans-regional material transfer and the risk of folding. Through the analysis and comparison by selecting a better simulation scheme, it is found that the amount of material transfer in the transition zone is significantly reduced to avoid the folding defect in the transition zone.
