摘　　要：应用有限元软件ABAQUS对圆管绕弯成形过程中的横截面畸变进行了数值模拟。研究结果表明,随着弯曲角度的增大,最大截面畸变率也随之增大;随着相对弯曲半径R/D的增加,最大截面畸变率呈下降趋势;随着摩擦系数的增大,最大截面畸变率变化不大。实验验证表明,模拟结果与实验结果基本吻合。By using the software ABAQUS,a simulation analysis for the tubes＇cross-section deformation is carried out,which results indicate that the maximum distortiont rate of cross-section will increase with the increase of bending angle;with the increase of R/D,the maximum distortion rate of cross-section tend to decrease;with the increase of the friction coefficient,the change of the maximum distortion rate of cross-section isn＇t obvious.It is rectified through experiments that the simulation result is basically identical with the experimental results.
