摘　　要：目的建立"阶梯式形变"多曲方丝弓(MEAW)三维有限元模型,为分析MEAW应力应变的变化提供良好平台。方法应用Auto-CAD构图软件建立MEAW的几何模型,利用ANSYS软件进行实体单元网格划分,定义初始条件、边界情况,确定材料属性。结果成功建立"阶梯式形变"MEAW三维有限元模型。结论利用Auto-CAD软件和ANSYS软件建立了"阶梯式形变"MEAW三维有限元模型,方法简单、容易操作且省时,有限模型的建立为研究分析其应力应变的变化提供了较好平台。Objective To construct three dimensional finite element model of ＂a multistep deformation＂ MEAW,to pro- vide a good platform to analyze stress-strain of MEAW. Methods Established MEAW geometric model with Auto-CAD com- position software, applicated ANSYS software partition entity unit, defined initial condition and boundaries condition, determined materials attribute. Results ＂A multistep deformation＂ MEAW three dimensional finite element model was constructed suc- cessfully. Conclusion Application of Auto-CAD software and ANSYS software construct ＂a multistep deformation＂ MEAW three dimensional finite element model. The method was simple, easy to operate and less time. It provides a good platform to study and analyze the change of stress-strain.
