ABAQUS based simulation of aluminum alloy age‐forming is meaningful to predict the forming and springback .For the simulation ,the boundary conditions have great effects on prediction accuracy .The structure of part and the actual working condi‐tions determine the boundary conditions .This paper presents the feasible boundary conditions for age‐forming simulation of the non‐symmetrical panel ,and the result shows the deviation is lower than 0.5mm ,satisfying the application requirement .
