Based on the surface roughness structure parameters and surface lubrication process parameters, the differential conditions of surface assembly characteristics were set in combination with the process characteristics of aeroengine bolts for several times. The experimental study was carried out based on the TC4 single bolt tightening test system. Results showed that when torque control method was used, the equivalent friction coefficient of tightening assembly decreased and was prone to stabilize with the decrease of surface roughness and the increase of surface lubrication levels, thus improving the stability of tightening torque coefficient. Sufficient lubrication of tightening friction surface with lower surface roughness, sufficient lubrication of thread pair and use of high temperature graphite grease can effectively reduce the fluctuation of tightening torque coefficient and improve the consistency of preload force of aeroengine bolt set connection.
