以端盖锻件的热闭式模锻成形为例,采用数值模拟方法,对锻件的成形过程中的各项宏观变化规律,如损伤,载荷,温度场等进行了揭示,预测了锻件的宏观缺陷。同时,对其成形中的动态再结晶过程进行了模拟。从微观的角度揭示了锻造过程中工艺参数对微观变化的影响规律。 Taking the heat closed die forging of end cap forgings as an example, numerical simulation method was used to reveal various macroscopic changes in the forming process of forgings such as damage, load, temperature field and so on. The macro defects of forgings . At the same time, the dynamic recrystallization in its forming process was simulated. From the microscopic point of view, the influence of process parameters on microscopic changes during forging process was revealed.
