RESEARCH ON INFLUENCES OF DRILLING VERTICALITY ON BEARING CAPACITY OF RIVETS UNDER THE AXIAL VIBRATION LOAD
The aircraft’s inlet structure is connected to the engine sleeve using countersunk rivets. During maintenance
fatigue fractures were discovered in some rivets. It suggests that the inadequate perpendicularity of rivet holes during manufacturing causes the rivet misalignment
reducing the load-bearing capacity
and leading to fatigue fractures under aircraft vibrations. The finite element simulation was used to study the effect of inclined rivet holes on the load-bearing capacity
simulation results show that inclined holes cause uneven stress distribution across the rivet section. The higher the tilt angle
the higher the maximum stress and the more uneven stress distribution on the rivet head section. Fatigue tests under axial loads at different tilt angles demonstrated a reduction in the rivet’s fatigue life due to the hole inclination. The study concludes that non-compliance with perpendicularity standards during hole fabrication results in uneven stress distribution
decreasing load-bearing capacity. Therefore
the strict control over rivet hole perpendicularity during the aircraft manufacturing is crucial to ensure structural reliability.
