发布时间：2019-05-14 12:16
【摘要】：开发了一种铸锻联合成形工艺的协同仿真技术。采用ProCAST软件的CAFE模块进行铸造模拟,获得初始不均匀的铸态晶粒尺寸。编译了一组Fortran程序作为Deform-3D软件的功能模块,用以建立初始不均匀铸态晶粒尺寸的分布与Deform-3D锻造模型之间的耦合。通过对Deform-3D的二次开发,实现了锻造过程中微观组织演变的数值模拟。最终实现了对动态再结晶晶粒尺寸和动态再结晶体积分数的预测。采用开发的协同仿真技术对截齿齿体的铸锻联合成形工艺进行了数值模拟分析。模型分别采用了初始均匀的晶粒尺寸和由铸造模拟获得的初始不均匀的晶粒尺寸,获得了两种模型的动态再结晶晶粒尺寸和动态再结晶体积分数的分布。通过对比分析,证明了铸锻联合成形工艺晶粒分布预测协同仿真技术的可行性。
[Abstract]:A collaborative simulation technology for casting and forging combined forming process is developed. The casting simulation was carried out by CAFE module of ProCAST software, and the as-cast grain size was obtained. A set of Fortran programs are compiled as the functional modules of Deform-3D software to establish the coupling between the initial uneven as-cast grain size distribution and the Deform-3D forging model. Through the secondary development of Deform-3D, the numerical simulation of microstructure evolution in forging process is realized. Finally, the prediction of dynamic recrystallized grain size and dynamic recrystallized volume fraction is realized. The combined casting and forging process of cutting teeth is simulated and analyzed by using the developed collaborative simulation technology. The initial uniform grain size and the initial uneven grain size obtained by casting simulation were used in the model, and the distribution of dynamic recrystallized grain size and dynamic recrystallized volume fraction of the two models were obtained by using the initial uniform grain size and the initial uneven grain size obtained by casting simulation, respectively. Through comparative analysis, the feasibility of collaborative simulation technology for grain distribution prediction of casting and forging combined forming process is proved.
