Calculations of the impact of friction and wear on energy consumption, economic
expenditure, and CO 2 emissions are presented on a global scale. This impact study covers …

Pre-stressed bolted joints are widely used in civil structures and industries. The tightening
force of a bolt is crucial to the reliability of the joint connection. Loosening or over-tightening …

Loosening failure is a serious failure mode of bolted joints. The anti-loosening performance
of bolted joints can be evaluated quantitatively by measuring their critical transverse loads …

针对航空发动机装配过程中出现的螺栓预紧力误差大, 控制精度低等问题, 基于TC4
钛合金单螺栓连接工艺实验, 分析了不同拧紧策略对装配预紧力大小及稳定性的影响 …

The use of bolted flange connections in the offshore wind industry has steeply risen in the
last few years. This trend is because of failings observed in other modes of joints such as …

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 …

The clamping force of the bolted joint is a key factor in maintaining its service performance.
However, when the torque wrench is removed after tightening, there will always be a certain …

Due to its strength advantage, high strength bolts are able to provide larger clamping force.
However, the changing behavior of friction coefficient during repeated tightening will …

Purpose Bolted joints are the most common type of mechanical connections, and improving
the anti-loosening performance of bolts for the reliable performance of mechanical and …

This paper investigates the self-loosening of threaded fasteners subjected to dynamic shear
load. Three kinds of typical coatings, PTFE, MoS2, and TiN applied to bolts and nuts, are …
