An experimental approach was adopted to understand service damages such as crack initiation and surface degradation of bolted joints used in the junction technology of aircraft air bleed valve systems. A vibratory testing stage combined to Digital Image Correlation (DIC) focus on an experimental model device of valve body/actuator body junction. DIC coupled with in situ tribological observations and a Finite Element Model (FEM) has been used to identify more clearly local contact conditions. This approach has enlightened peeling-off and micro-slips instabilities under vibratory loadings, leading to third body formation in bolted joints contacts. The morphology of such third body is placed at the focus of damages observed in involved air bleed valve systems.

“…Improper preload can degrade the behavior and life span of the joint and lead to joint problems, such as material failure, fastener loosening, joint separation, leakage, rattle, and fatigue failure [2] to [4]. It has been reported that up to 90% of bolted joint failures are caused by incorrect initial bolt tightening [5]. In the assembly of miniature precision equipment, performance degradation can be attributed to nonuniform stress, which is caused by the scatter of bolts preload.…”

In this work, the improved torque method based on a mathematical model is proposed for preload control in the precision assembly of miniature bolt joints. The mathematical model was used for predicting the friction-compensated control torque. The predicted control torque is a function of preload and torque gradient which is determined by the friction of contact surfaces. Thus, the effect of friction on preload error was reduced, and the bolts preload scatter due to frictional variables of the bolts was decreased. Experiments were carried out to verify the proposed method using the bolts with a thread of M1.6, and the results show that the scatters of preload were less than ±13.0% in the elastic range, which is more consistent than the conventional torque method. The preload control error for most bolts was less than 10%.
