| 摘要: |
| 刚性包带式连接装置是适应运载火箭重型化发展趋势而提出的新型星箭连接方式。建立预紧状态下的刚性包带及端框结构非线性静力学模型，分析其在轴向承载时的结构强度和连接刚度特性，并结合轴对称等效和参数化建模技术，通过优化截面形状参数提升对整体连接性能。结果表明：包带与端框之间"线-面"接触位置的结构应力较为集中；增加包带结构轴向尺寸、减小包带V形槽角度和加深包带与端框咬合配合深度能够有效提升刚性包带连接刚度；通过截面形状优化，可在结构强度和质量限制条件下，使刚性包带连接性能提升70%以上. |

| Abstract: |
| The Rigid Clamp Band Connection Device (RCBCD) is a novel satellite-rocket connection method adapted to the heavy lift trend of the launch vehicle. The static analysis model for the Rigid Clamp Band (RCB) and the Docking Ring (DR) under preloading state is established, and the structural strength and connection stiffness characteristics under the axial loading are analyzed, and the axisymmetric equivalent and parametric modeling techniques are combined to optimize the section shape parameter, which improves the overall connection performance. The results show that the structural stress concentrated on the "line-to-face" contact position between RCB and DR. Increasing the axial dimension of RCB, reducing the V-type angle and deepening the occlusion depth of RCB and DR can effectively improve the connection rigidity of RCB. By optimizing the section shape, the connection performance of RCBCD can be improved by above 70% under the structural strength and mass constraints. |
