| 摘 要： | 本文针对金属一复合材料多钉连接件的载荷分布进行试验研究和数值分析.首先,通过应变电测法测量了一列三螺栓双剪连接件的钉载分配比例,揭示出该比例随载荷变化的现象和特征.然后,建立了考虑多面接触的三维实体有限元模型,在计算分析中考察钉一孔间隙分布、预紧力和摩擦对钉载分配的影响规律.计算结果表明:初始间隙是影响钉载分配比例的最...

| Abstract: | This paper deals with the load transfer and fastener load distribution of the multiple-bolted joints by means of the experimental study and finite element analysis.The specimens are the composites to titanium double lap joints with a column of three bolts.The fastener load distribution and the its alteration with external loading are determined in the experiments by the strain gauge measurement.Then the three-dimensional finite element model consisting of multiple contact interfaces is established.The effec... |
