转体施工是一种先进的桥梁施工方法,转体施工的关键构件就是承载整个转动重量的转动球铰,其设计的合理性将直接影响到施工质量及安全性.本文以现有有限元计算理论为指导,结合工程实例,利用有限元分析程序MIDAS建立了该桥转台的空间有限元模型,给出了球铰在特定荷载工况下的计算结果,并对计算结果进行了对比分析,为以后同类结构球铰的设计提供参考.
轉體施工是一種先進的橋樑施工方法,轉體施工的關鍵構件就是承載整箇轉動重量的轉動毬鉸,其設計的閤理性將直接影響到施工質量及安全性.本文以現有有限元計算理論為指導,結閤工程實例,利用有限元分析程序MIDAS建立瞭該橋轉檯的空間有限元模型,給齣瞭毬鉸在特定荷載工況下的計算結果,併對計算結果進行瞭對比分析,為以後同類結構毬鉸的設計提供參攷.

Level swing method construction is an advanced bridge construction method. The key component of level swing method construction is the hinge which carries the weight of the entire rotation.The design rationality of the hinge directly affects the quality and safety of construction. Under the guide of the existing finite element calculation theory, based on certain engineering example, the three dimension finite element model has been built,using the finite element analysis program MIDAS. Its calculation results are given under the specific load condition. Its calculation results are analyzed by contrast, which provides reference for the design of similar structure hinge in the future.
