摘要:

Bolted connections are widely used in various mechanical structures due to their structural and strength advantages. However, the bolted connection will fracture and lead to failure under the action of excessive load, which affects the service reliability of the structure. In this work, the mechanical performance of single-lap bolted connection under impact load was elaborated by finite element analysis. In order to obtain a more reliable connection, different parameters were considered, i.e. tightening torque, load amplitude, friction coefficients for the contact surfaces, etc. In order to investigate the effect of various friction coefficients on the structural slip under impact load, orthogonal tests were designed and carried out. The results showed that the influence ranking of each friction coefficient on the structural slip was as follows: contact friction coefficient, thread friction coefficient, head friction coefficient, and bearing surface friction coefficient. The performance under impact load was positively related to the magnitude of the tightening torque. Within a certain impact load amplitude threshold, the structural performance was relatively stable. The reference basis for the reliability design of bolted connections based on the service and structural performance can be obtained from the finite element analysis results. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
