摘要: 用有限元素法作为二维问题研究受拉伸载荷的多紧固件接头的力的分配,已获得了满意的数值解。在此基础上,本文集中研究了复合材料多紧固件接头的热载荷分配。 1.计算模型 研究具有n排紧固件的对称接头,作如下假设:(1)问题是线性弹性的;(2)孔位置准确,且与紧固件紧密配合,无间隙;(3)被连接的每块层板处于均匀温度场,

Abstract: Load distribution among fasteners for multi-fastener Joints under thermal effects is investigated.Elasticity of both plate and fastener has been considered by the use of FEM.Factors that influence the distribution such as plate properties and dimensions, fastener intervals and arrangements, etc. are examined and reported. The analysis method and computer program can be applied extensively.
