Research on Process Planning Method of Aerospace Engine Bolt Tightening Based on Digital Twin

Aerospace engine is the source of power for development national defense and aerospace. Engine bolt tightening an important part aerospace production process. At present, most methods engines are manual or traditional rigid tightening, which lead to problem low efficiency large deformation. This paper proposes a process planning method based on digital twin, including flexible mechanism design, sequence optimization, establishment twin system mechanism, etc. The suitable different types engines. Based deformation stress cabin section during reduced. work completed in system, real-time communication physical space synchronizes operations them. After residual pre-tightening force bolts detected ultrasonic method. results show that proposed can solve problems cabin’s Furthermore, it provides technical reference theoretical basis technology engine.
