Abstract:

Aiming at the problems that welding is not suitable for aluminum alloy structure and the nodesare prone to misalignment under shear connection of existing fasteners, the assembled rivets for shearconnection are designed, and the structure,working principle and preload determination method ofassembled rivets are given. By carrying out shear specimen test research and finite element analysis, theassembled rivets shear connection load and displacement curves, force transfer mode, damage mechanismand morphology, to determine the reasonable riveting order of the assembled rivets, and to verify thevalidity of the finite element model and analysis results. According to the research results, in practicalapplication, it is recommended that the ratio of the sum of the plate thickness of the shear connection inthe same force direction to the diameter of the assembled rivets is 1. 00——1. 25. The influencing factors ofassembled rivets shear performance were analyzed, through numerical fitting to get the assembled rivetsbearing capacity calculation formula. The selection specifications of shear connection of assembled rivetsare given.
