摘　　要：基于“日”字形截面型材绕弯成形原理,利用ABAQUS软件平台建立与实际加工相符合的绕弯成形有限元模型,研究了复杂截面型材绕弯成形制品应力分布和芯模结构对制件厚度变化的影响规律。结果表明,采用自锁型柔性芯模绕弯成形制件质量较好。Based on the bending principle of“日”shaped section,the finite element model of rotary bending is established by using ABAQUS software platform,which is consistent with the actual processing parameters.The influence of stress distribution and core die structure on the thickness variation of the parts formed by rotary bending complex section profiles is studied.The results show that the quality of the parts formed by self-locking flexible mandrel is better.
