趸船引桥结构强度有限元计算及结构改进方案研究

Finite Element Analysis and Improvement Project Research for the Structural Strength of a Barge's Approach Bridge

以某趸船引桥结构为研究对象,在两种载荷状态下对引桥结构强度进行有限元直接计算,在此基础上,就引桥连接方式以及车辆行进方式做了两组对比研究并得到相关结论。最后,就结构强度计算中发现的问题提出结构改进方案并进行效果验证,希望可以为此类结构的设计和使用提供参考。

The strength of a barge＇s approach bridge at two kinds of loading conditions is calculated by the FEM in this paper. On this basis, a comparative study of two groups on the bridge approach and way of moving vehicles is done, and relevant conclusions are got. Finally, structure improvement program is put forward and verified on the problems found in stress calculation. The conclusion provides the reference for design and application of this kind of structures
