摘　　要：利用数值模拟方法对锻造过程中的锻造温度场、V型砧砧宽和布砧方式等工艺参数对锻件心部质量的影响进行了研究。结果表明,温度梯度、宽大V型砧和交替布砧的方式能够有效地提高锻件心部的压实效果。The influence of the technological parameters during forging,such as forging temperature field,V shaped anvil width and anvil distribution mode on the quality of forging core is researched by numerical simulation.The result shows that the temperature gradient,V shaped wide anvil and alternating anvil distribution can effectively improve the compaction effect of forging core.
