| 摘要: |
| 采用MSC.Patran参数化建模和遗传算法进行包带式星箭连接结构优化设计。首先给出了包带连接结构二维轴对称模型优化设计过程中涉及的V形卡块刚度等效、包带预紧力模拟和载荷施加方法，以及强度和刚度约束条件、优化目标等内容；然后以某直径为3m的包带连接结构为例进行了优化设计，并分析了对接框内延伸段长度和端头高度对应力及变形的影响；最后建立三维有限元模型进行静力分析。结果表明（1）该方法适用于包带连接结构的优化设计；（2）增加对接框内延伸段长度和端头高度能够提高整体连接刚度；（3）三维有限元模型与轴对称模型计算结果一致，验证了轴对称模型分析方法的正确性，以及V形卡块等效和预紧力模拟方法的有效性。 |

| Abstract: |
| A new application based on the parameter modeling method of MSC.Patran and generation algorithm was proposed to design the clamp band joint. First, finite element techniques for 2-dimension axisymmetric analysis of clamp band joints were developed, including the modeling of V-clamp, strap pre-tension and loads, and the optimizing constrains and objectives were also introduced. Then a clamp band joint with the diameter being 3m was designed via the presented method. Finally, a 3-dimension finite element model of the designed clamp band joint was established and analyzed. It indicates that the method is applicable to the design of clamp band joints, that the connective stiffness is strengthened by increasing the length and height of the inner ring of the interface rings, and that the modeling method is proved to be valid by the agreements of the finite element analysis results of 2-D model and 3-D model. |
