GH4169外螺纹滚压过程ABAQUS有限元仿真模型建立及验证
Establishment and Verification of ABAQUS Finite Element Simulation Model for GH4169 External Thread Rolling Process
摘要
Abstract
In order to reveal the rolling forming mechanism of GH4169 outer thread in depth,the finite element simulation model of rolling process of GH4169 outer thread was established by ABAQUS and verified by experiment.During the rolling process,the contact area between the roller and cylindrical workpiece changes constantly,which belongs to the complex contact type.Therefore,the key technologies such as material constitutive model,solution type,grid partition and adaptive grid,contact and boundary conditions during the establishment of finite element model are introduced in detail.The validity of the simulation model is verified by energy method,external thread shape and maximum radial force.关键词
