Cracking Analysis of Automobile Part with Bending Deformation

QIU Xiao-gang,WANG Liang-yun (Pangang Group Research Institute Co.,Ltd.,Panzhihua 617000,China)  
The bending deformation of automobile part was analyzed by the finite element simulation method,the influence of bending radius,material properties and thickness size on bending deformation was discussed.Based on the analysis results,it was one of the reasons for the bending crack,that small bending radius incurred increase of tensile stress in the part's outer surface.Therefore,the properties of Q345 steel can not meet the requirements to bending of the automobile part.
