Abstract: |
The lift and flip process of fuel tank based on its rolling equipment is studied in this paper. A feasible intensity checking method of the screw thread fasteners is obtained by theoretical and mathematic methods. And the structure safety of the rolling equipment and the fuel tank at the connection part is studied with the finite element method, and the good performance is testified, which proves the feasibility of the lift and flip process of fuel tank based on its rolling equipment. |
Key words: rolling equipment;fuel tank;flip |
