摘　　要：混凝土球铰磨心是转体桥梁的关键构件,对表面接触应力的准确分析与掌握直接影响工程设计以及施工阶段的质量与安全。以球铰磨心表面接触应力为目标,基于非赫兹接触的理论解法及有限元数值模拟,对球铰接触应力进行计算,做出球铰接触应力分布曲线,对比不同球铰设计参数的最大接触应力值,分析球铰设计参数与最大接触应力的关系。The grinding center of concrete spherical hinge is the key component of the swing bridge,and the accurate analysis and grasp of the surface contact stress will directly affect the quality and safety of engineering design and construction stage.Setting the surface contact stress of spherical joint as the goal,based on the Non-Hertzian Contact theory and the finite element numerical simulation,the contact stress of the spherical hinge is calculated,and the contact stress distribution curve is made.The maximum contact stress values of different design parameters of the spherical hinge are compared,and the relationship between the design parameters of the spherical hinge and the maximum contact stress is analyzed.
