摘要: 复合材料杆件接头一般采用胶接连接。为了进一步提高杆件与接头的连接强度,对复合材料杆件接头的结构形式进行设计,提出了三种结构设计方案。为了比较三种方案的优劣,根据当前需求,开展了有限元分析,并制作了拉伸试样,进行了拉伸试验。试验结果表明,与前两种设计方案相比,第三种结构设计方案的工艺稳定性较高,拉伸承载能力最高,拉伸性能稳定,设计方案最优。三种结构设计方案的有限元分析结果与试验结果基本一致,有限元分析方法合理有效,提高了研究效率。有限元分析和试验结果为后续的研究工作提供了依据。

Abstract: Composite rod joints are generally joined by glued joints. In order to further improve the connection strength between the rod and the joint, the structure design of the composite rod joint was carried out and three structural design schemes were proposed. In order to compare the advantages and disadvantages of the three design schemes, finite element analysis was carried out, tensile specimens were made and tensile tests were carried out according to current requirements. The test results show that, compared with the first and second design schemes, the third structural design scheme has higher process stability, the highest tensile load capacity and stable tensile performances, making it the optimal design scheme. The finite element analysis results of the three structural design schemes are basically consistent with the test results, and the finite element analysis method is reasonable and effective, which improves the efficiency of the study. The results of the finite element analysis and the test results provide the basis for the subsequent research work.
