加热弯管弯曲过程的有限元分析

Analysis of thermal-bending tube forming processes

借助ANSYS软件对金属成形过程中的大变形、接触等非线性问题的处理,采用三维梁单元、三维塑性直管单元、三维弹性曲管单元、三维壳单元及三维点对面单元分析了加热弯管弯曲过程及接触问题,所得参数为加热弯管机的优化设计提供了理论基础.

The thermal-bending tube forming processes and contact question are analysed with the help of ANSYS finite element software, which ralate to beam element 3D, struetural pipe plastic straight 3D, structural pipe elastic elbow 3D, Shell element 3D and contact elements 3D pt-to-surf. Obtaining parameters lay theoretical basis on optimum design of thermal-bending tube machine.
