【摘要】 运用非线性有限元法,波纹管采用三维壳单元Shell93,网套采用空间梁单元Beam189,利用耦合和约束理论,在ANSYS中建立金属软管的有限元模型,对金属软管的拉伸、压缩、弯曲等特性分别进行有限元分析,得到金属软管的特性曲线,并将分析结果与试验结果进行比较,证明了有限元建模分析结果以及耦合和约束理论运用的合理性,为金属软管的力学性能和设计分析的进一步研究提供了参考。更多还原

【Abstract】 Using the non-linear finite element method(FEM),together with the coupling and constraint theory,the finite element model of the metallic hose was put forward.It adopted the Shell93 element(for bellows) and Beam189 element(for metal net) in ANSYS,and finite element analysis of metallic hose was made,including pulling,compressing and bending.The comparison of mechanical characteristic curves between the analysis results and the experiments proves the validity of the finite model and the exertion of the coupling and constraint theory.The article provides a reliable reference for the mechanics performance and the further research of the metallic hose.更多还原
