摘要
采用三维壳单元shell93和空间梁单元beam89,运用耦合和约束方程理论,利用ANSYS的参数化设计语言(APDL)对金属软管进行了参数化的三维实体建模。对金属软管的力学特性进行了分析计算,并将计算结果与实验数据相对照,确定了有限元方法的可靠性。根据分析结果,对金属软管的特性进行了总结,结论对金属软管的设计和应用具有重要参考价值。
Based on the theory of coupling and constraint equation, the paper puts forward a finite element model (FEM) of metallic hose with the element of shell93 and beam189. The comparision of mechanical characteristics between the results of analysis and the experiment data indicates that the FEM is reliable. The conclusion drawn from the study is very valuable for the design and application of the metallic hose.
