Dataset on force and torque for fastener clamping

Description

This repository comprises experimental data acquired to investigate the critical angular clamping speeds for fasteners by the use of design of experiments methodology (DOE). The stick-slip phenomenon is considered as a critical factor limiting the angular screw clamping speed. The stick-slip was quantified using the stick-slip factor as a function of the amplitude ratio by the frequency of the friction torque data. An investigation was carried out involving the influencing variables on the stick-slip factor, on torque, and on clamping force (preload): friction coefficient, clamping angular velocity, cathodic electrodeposition, hardness of the bolt-head bearing plate.
