Finite Element Modeling of Tower Bolt Connection and Dynamic Load Analysis

摘要: 考虑螺纹升角建立螺栓联接的三维有限元模型，利用ABAQUS进行有限元分析，采用直接加载的方式施加预紧力，模拟螺纹联接副的承载力，并与Yamamoto解析法进行了对比验证。在此基础上施加横向动态载荷，研究了动态载荷作用下螺纹副不同的摩擦系数对应的螺纹承载力的变化情况。

Abstract: Considering the thread Angle to establish the three-dimensional finite element model of bolt connection, using ABAQUS finite element analysis, with the method of direct load exerted preload, simulation of the bearing capacity of the threaded connection vice, and compared with Yamamoto analytic method is used for validation. Applying transverse dynamic loads, on the basis of dynamic loads is studied under the action of thread pair of different friction coefficient of the corresponding changes of the bearing capacity of screw thread.
