Analysis and Design of Large Space Structures with NonlinearJoints

将研究具有非线性节点的大型柔性空间结构的建模、分析和设计。对套筒接头进行的初步工作将得到扩展，销接头模型将得到开发。下一步，将基于伽辽金/牛顿-拉夫森频域方法的扩展，开发高效、准确的分析方法。最后，对改善阻尼特性的连接节点设计进行了研究。将探讨被动和主动设计策略。

The modeling, analysis, and design of large flexible space structures with nonlinear joints will be investigated. Preliminary work performed on sleeve joints will be extended and pin joint models will be developed. Next, efficient and accurate analysis methods will be developed based on extensions to the Galerkin/Newton-Raphson frequency domain method. Finally, the design of connecting joints for improved damping characteristics will be studied. Both passive and active design strategies will be explored.
