Abstract：

In this paper,the key techniques of numerical simulation in the rotary draw bending of aluminum alloy profile are studiedThe influence of finite element model and loading method on the simulation result is discussedAnd laws of side pressure and rear pulling force effect on geometrical defect in the rotary draw bending are analyzedThe result shows that the finite element analysis is proven to be a very effective numerical tool and has the same laws as that of the experimentFurther more,it is concluded that hexahedral body element is more effective than the sheet element in the rotary draw bending of FEM simulationFEM simulation will provide a technical basis for the practical application in the future
