The 3D Modeling of Dies Based on UG and Numerical Simulation of the Heat Rheological Forming of Titanium Alloy Vane Disk


Article Preview

The heat rheological forming of the TC11 titanium alloy vane disk has been studied. The dies of rheological forming were 3D-modeled based on UG and the heat rheological forming of the TC11 titanium alloy under a certain temperature and a low strain rate was analyzed by DEFORM 3D based on variation principle of rigid viscoplastic non-compressed material. A series of results including rheological forming procedure, equivalent strain field, temperature field and load-stroke curves of punch and cavity die, were obtained by finite element method. The deformation characteristic of the TC11 titanium alloy was well known and its heat rheological forming process and parameters were determined. Moreover, the local underfilled phenomenon in practical manufacture was predicted and analyzed, and we found that the defects could be restricted by reducing the forming velocity.
