文摘

This paper presents a numerical method to predict the distortions of alloy blades, caused by uneven temperature distribution and its thermal stress in cooling phase. A simplified thermo-mechanical model is presented, considering the actual production conditions. A simulation model of TC11Titanium Alloy Blade is established and performed to evaluate the transient temperature field and deformation by using ANSYS. The simulation results also are compared to the experiment results at the end.
