摘要: 利用MARC/AutoForge3.1元件,使用三維彈塑性熱力耦合有限元方法模擬采用新型油井管用鋼33Mn2V熱軋制管的雙道次張力減徑過程,并直觀地顯示了三維管件材料內部和表面不同方位的金屬流動、應力、應變和溫度演化情況.模擬結果表明:不論是工件表面還是內部,在張力減徑過程中金屬流動、應變、應力和溫度分布都是不均勻的;分析成品管顯微組織時應當考慮這些因素.

Abstract: Using the software MARC/AutoForge 3.1, a three-dimensional thermo-mechanical coupled elasto-plastic Finite Element Method (FEM) was used for the simulation of a two-pass tube tension-reducing process of 33Mn2V steel for oil well tubes. The simulated results intuitionally visualize the metal flow and dynamic evolution of strain, stress and temperature, especially inside the work-piece, and show that their non-uniform spatial distributions on the longitudinal and transverse sections are a distinct characteristic of the tube tension-reducing process.
