Abstract  

A three dimensional finite element model (FEM) was established to simulate the forming process of titanium alloy hollow monolithic structure. The influence of process parameters on this process was analyzed by finite element method code MSC.Marc in which a rigid–viscoplatic constitutive equation was implemented. The results demonstrated that with the increase of twisting velocity, the torque on the hollow structure changes indistinctively. In case of increasing die velocity and target strain rate, the forming force of hot forming and gas pressure of superplastic forming will increase. On the contrary, along with the increasing of temperature, the forming force decreased. In case of temperature above 900 ℃, the influence of temperature on the forming force and gas pressure was weaken. Based n FEM, at the conditions oprocess paramtrs, like torsions speed of 4.376×10−3 rad/s, hot forming die velocity of 2.12×10−1 mm/starget strain rate o1.0×10−3 s−1, as well as at the temperature of 925 ℃, a simulacrum f hollow mnolithic structure ftitanium alloy was prepared, the thickness distribution of the ace sheet of the obtained part was in good agreement with the simulated results.
