Contact Analysis and Experimental Research on Connector of Prefabricated Mechanized Bridge

为研究某装配式机械化桥连接器结构的力学特性,基于ANSYS接触分析理论建立了该连接器受力分析的三维有限元模型,并对不同荷载作用下连接器的受力情况进行了数值分析,得到了不同荷载工况下的关键部件的应力分布;通过制作连接器实体模型,进行了不同荷载工况下的试验,得到了连接器关键部件的试验应力值和关键结构的应力随荷载的变化规律;通过仿真结果与试验数据的对比研究,研究结果表明,连接器仿真的建模和分析策略具有可信性,能够作为连接器的进一步分析的方法,为下一步的分析提供了理论支撑。

In order to study mechanical ture, first we built a 3-D finite model of numerical analysis of the connector were properties of a prefabricated mechanized bridge connector structhe connector based on ANSYS contact analysis theory, and the carried out under different load cases, which provided stress distribution of key parts of connector. Then a solid model was made to conduct experiments under different load cases, which provided experimental stress and the variety law of stress of key parts of connector, and according to the contrast of simulation results and experimental data, the simulation strategy of modeling and analysis of connector is dependable, which can provide methods and theoretical supports of further analysis.
