摘　　要：针对大型转子锻件在锻造过程中常用的几种压实方法,选用目前常用的几种心部压实指标,利用DEFORM-3D软件分别模拟了199 t钢锭单锤压下、一次镦拔和两次镦拔过程,通过对模拟结果的比较分析,对比不同拔长方法的压实效果,为实际生产时压实方法的选择和合理搭配提供依据。Aiming at several compaction methods commonly used in the forging process of large rotor forgings,several commonly used core compaction indexes are selected.DEFORM-3D software was used to simulate the single-hammer screw down,one-time upsetting-drawing and twice upsetting-drawing processes of 199 t steel ingot.Through the comparative analysis of the simulation results,the compaction effects of different drawing methods are compared,which provides a basis for the selection and reasonable combination of compaction methods in actual production.
