Abstract：The temperature field and stress field of quenching processes of ZL205A aluminum alloy large complicated
workpiece are simulated by finite element method based on ABAQUS software. The temperature field distribution of the
workpiece at different times is analyzed. Four key points based on the structure characteristic of the workpiece are chosen
for the cooling curves. The cooling curves of the thick-wall, strengthening rib and thin-wall of workpiece are investigated.
The maximum deformation and residual stress after quenching are predicted by finite element simulation. The maximum of
quenching deformation at radial direction of ZL205A aluminum alloy large complicated workpiece. The six components of
quenching residual stress are compared, the normal stress is greater than the shear stress. The quenching processes of thickwall
workpiece with different heat transfer coefficients are investigated. The cooling rate of thick-wall workpiece increase
with the increase of the heat transfer coefficient, but the amplitude isn’t obvious.
