WebSep 15, 2010 · Contact pressure or clamping force and displacement at the interface or relative slip are two important factors which control the fretting wear and the fretting fatigue. This paper describes the effect of clamping force (tightening torque) on the fretting fatigue behaviour of bolted assemblies. WebAug 21, 2024 · For fretting corrosion to occur, the following conditions to be satisfied: Interface must be under load Relative motion must occur and should be sufficient enough to produce deformation on the surface Fretting corrosion is common in: Riveted joints/structures Bolted joints/flanges
WebJul 1, 2002 · Bolt connection plays an important role in assembly structures. Under long-term vibrations, bolted joint interface will change due to fretting-induced friction and wear behavior. This leads to changes in the dynamic characteristics of assembly structures, which increases the difficulty of control of the structure. WebApr 14, 2024 · 3.1 Fretting Fatigue Life. Figure 2 shows the S-N curves obtained for specimens with the two surface treatments, as identified by plotting the mean values of fatigue life for each of the six conditions tested. Also shown is the standard curve for Detail Category B given in CSA S16-14 for reference. Of significance is the fact that the data …
