| Abstract: |
| Rivet assembly direction is one of the factors that influence the force and deformation of the rocket cabin. Taking Φ4mm 2A10 rivet as the research object, the influence mechanism of two different rivet assembly directions on riveting performance of structural parts was analyzed based on ABAQUS software. The results of analysis indicate that, the assembly of the rivet head towards the side of the thin structural part is conducive to the uniform expansion of the nail rod, and it is beneficial to improve the riveting quality of carrier rocket cabin. |
