Simulation Modeling of Transient Temperatures and Stresses Fields during Quenching 7075 Aluminum Cone-shaped Shells

摘要：

The technological and economical pressures in manufacturing industry require an optimization of existing production processes. For this purpose, Thermal elastic-plastic constitutive equations are established to gain insight into the quenching operation of a production system. The finite element model is established to model transient 3-D temperature ad stress fields during quenching of the cone-shaped shells. The X-ray diffraction method is applied to measure the residual stresses of coneshaped shell. And the measured residual stresses of quenched cone-shaped shell show a good agreement with those simulated by FEM. The example of FEM application in this paper offers theoretical basis and technological parameters for practical production, and makes it possible to optimize the process parameters of heat treatment of cone-shaped shells to control quality in the weapons production.
