摘　　要：通过有限元软件ABAQUS建立高强螺栓摩擦型连接的非线性有限元模型,并通过试验验证建立的有限元模型的准确性和适用性,最终建立高强螺栓摩擦型连接在摩擦阶段和滑移阶段的力-位移曲线简化模型。其意义在于:1)为结构分析人员提供较为准确的节点简化处理方法,在保证准确性的前提下,提高分析效率;2)将简化模型应用于吊车梁制动板与排架柱连接螺栓的受力分析,明确螺栓的实际受力情况,有效解决螺栓松动问题。The non-linear finite element model of high-strength bolts friction type connection is established by finite element software ABAQUS,and the accuracy and applicability of the finite element model are verified by experiments.Finally,the force-displacement curve simplified model of high strength bolt friction connection in friction and sliding stages is established.Its significance lies in:1)Providing structural analysis with more accurate simplified treatment method of joints,improving analysis efficiency on the premise of ensuring accuracy;2)Applying simplified model to stress analysis of bolts connecting brake plate and bent column of crane girder,clarifying the actual stress situation of bolts and effectively solving bolt loosening problem.
