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,
Using finite element method as a two-dimensional problem to study the force distribution of multi-fastener joints subjected to tensile loads, a satisfactory numerical solution has been obtained. On this basis, this paper focuses on the thermal load distribution of composite multifilament joints. 1. Computational Models The symmetric joints with n rows of fasteners are studied for the following assumptions: (1) the problem is linear and elastic; (2) the hole location is accurate and closely matches the fasteners with no gap; (3) Each connected slab is in a uniform temperature field,
