| 摘 要： | 在考虑螺栓与孔壁间的非线性接触、摩擦、干涉配合和螺栓预紧力等因素影响的基础上,利用非线性有限元软件MSC.Marc构建螺接搭接件的三维有限元分析模型.数值模拟结果与试验结果的对比表明,文中所建三维模型能有效地模拟搭接件的表面应变、载荷传递和第三弯矩等三维力学特性,同时搭接件的三维应力、应变特性及干涉配合和螺栓预紧力对载荷传递比的影响规律也进行了讨论,计算结果和结论可作为该类结构损伤容限设计的参考依据.

| Abstract: | Three-dimensional finite element model of a bolted joint has been developed in the non-linear finite element code MSC.Marc and attempts were made to validate it by comparing results with those of experiments and other finite element.Issues in modeling the contact between the joint parts,interference and pre-stress were presented.Experimental measurements of surface strains and load transfer ratio(LTR) were compared with results from finite element analysis.The results show that three-dimensional finite elem... |
