For the issue of organizational uniformity of TA15 titanium alloy complex force transmission structural components for a certain type of aerospace engine frame was studied, and based on numerical simulation software Deform-3D, the forging scheme was analyzed. And the contact conditions and lubrication of the forging process were optimized, finally a small batch production was verified. The results show that in the final stage of forming, the low temperature at the end face causes a sudden increase in load, resulting in a large temperature difference between the inside and outside of forgings, and the equipment pressure cannot meet the requirements. After optimization, the metal deformation is reasonable, the forgings are filled completely, the distribution of temperature field and equivalent strain field is improved, the forging load is reduced, the microstructure of forgings is uniform, and the mechanical properties are excellent, which improves the service reliability of the engine in complex environments.
