【摘要】：開發(fā)了一種鑄鍛聯(lián)合成形工藝的協(xié)同仿真技術(shù)。采用ProCAST軟件的CAFE模塊進(jìn)行鑄造模擬,獲得初始不均勻的鑄態(tài)晶粒尺寸。編譯了一組Fortran程序作為Deform-3D軟件的功能模塊,用以建立初始不均勻鑄態(tài)晶粒尺寸的分布與Deform-3D鍛造模型之間的耦合。通過對(duì)Deform-3D的二次開發(fā),實(shí)現(xiàn)了鍛造過程中微觀組織演變的數(shù)值模擬。最終實(shí)現(xiàn)了對(duì)動(dòng)態(tài)再結(jié)晶晶粒尺寸和動(dòng)態(tài)再結(jié)晶體積分?jǐn)?shù)的預(yù)測(cè)。采用開發(fā)的協(xié)同仿真技術(shù)對(duì)截齒齒體的鑄鍛聯(lián)合成形工藝進(jìn)行了數(shù)值模擬分析。模型分別采用了初始均勻的晶粒尺寸和由鑄造模擬獲得的初始不均勻的晶粒尺寸,獲得了兩種模型的動(dòng)態(tài)再結(jié)晶晶粒尺寸和動(dòng)態(tài)再結(jié)晶體積分?jǐn)?shù)的分布。通過對(duì)比分析,證明了鑄鍛聯(lián)合成形工藝晶粒分布預(yù)測(cè)協(xié)同仿真技術(shù)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.
