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.
