基于三维有限元模型的螺纹副承载力分布研究

摘要

结合 Pro/E、 Hypermesh、 Abaqus 软件各自的特点, 建立螺栓联接的三维有限元模型, 依据Yamamoto解析法分析了螺纹牙的变形并计算了螺栓内外螺纹的应变, 对螺纹副承载力分布进行模拟分析, 通过与Yamamoto解析法进行对比, 验证了模型的有效性, 为动态载荷下螺纹松动机理的研究打下了基础.%Considering various features of softwares including Pro/E, Hypermesh, and Abaqus, the 3D finite element model is built for the bolt connection.The Yamamoto analytical method is used to analyze deformation of the thread tooth and calculate the strain of the internal and external threads.The simulation analysis is performed on the bearing capacity of the thread pair.By comparing with Yamamoto analytical method, the model proves effective, which can build the founda-tion for study on the thread looseness mechanism under the dynamic load.
