Mechanical Analysis and Test Verification for Globe-Cone Joint Assembly of Electric Propulsion Systems

This paper investigates the sealing mechanism of the globe-cone joint of the electric propulsion systems. By carefully analyzing the nonlinear finite element model of the globe-cone joint assembly process, together with the engineering experience, the tightening torque range of the globe-cone joint is derived. Finally, the mechanics environment test and the leakage rate of detection are provided to verify and correct the effectiveness of the theoretical analysis results.
