Threaded fasteners are one of the most commonly used connection methods for mechanical
structures. Its primary function is to generate appropriate clamping forces and fasten the …

当前国内外精密/超精密加工技术的快速发展, 使得零部件加工精度和一致性得到显著提高,
装配环节对产品性能的保障作用正日益凸显, 相关研究越来越得到国内外学者的关注 …

With the rapid development of precision and ultra-precision machining technology at home
and abroad, precision and consistency of machined parts have been improved prominently …

The torque-tension relationship of threaded fasteners affects almost all engineering
disciplines. Tribological processes at fastener interfaces manifest as the system's friction …

This paper is focused on the experimental determination of the frictional properties of bolts,
following the ISO 16047 International Standard. The campaigns involved M14 X 2 8.8 class …

Adequate initial bolt preload is necessary to ensure the strength and stiffness of bolted
connections. In this study, an experimental torque control method was used to determine the …

The longitudinal resistance of ballasted tracks is due to the longitudinal interaction of rail-
fastener and ballast-sleeper. Longitudinal resistance is under the effect of various factors as …

Due to entry of body fluid like saliva, blood, etc. in the dental implant assembly lowers the
preload value, thus dental implant abutment tightening torque loses. In this article a novel …

Bolted joints are widely used in industries to connect and fasten two separated components.
During the assembly of bolted joints, torque wrench is commonly employed to control …

Bolts constitute a very important subset of mechanical fasteners. In order to tighten bolts, a
degree of bolt preload scatter is to be expected. Since the torque control of tightening bolts is …
