Abstract: The connection mode and performance of fiber-reinforced plastic connector connectors are studied and structural optimization are studied by the method of finite element analysis, and the analysis results are verified by the experimental method. The results show that mechanical connections are not suitable for joint connection structures of fiber-reinforced plastics that are mainly subject to stretch stress because of the concentration of stress at the bolts, and the plying connection methods of the double-tie board docking have smaller equivalent stresses, overall deformation and contact surface stress, and are not prone to peeling damage. It is shown that the docking of the double-connecting plate should be used as a joint connection method, which is consistent with the measured results, verifying the applicability of ANSYS finite element analysis in the performance study of fiber-reinforced connector connections. Finally, the joint structure is optimized based on the tie-up length, and the results show that the docking method of the double hooking plate with a connection length of 70 mm is optimized.
