Workers often tighten bolts to 75% to 80% of the bolt proof load. This works for many joints, but in some cases, external tensile loads reduce bolt clamping forces to zero. Something other than the 75 ...

Some joint-design considerations are universal; others vary with the assembly methods used. Each joining technique has particular design requirements, while certain joint requirements may suggest a ...

RAILWAY AGE, OCTOBER 2023 ISSUE: Rail fastening system technology continues to evolve, delivering a tight hold and longer track life in heavy-haul freight, high-speed passenger rail and transit ...

The scatter of bolt clamping force tightened by the conventional torque control method very often causes loosening and fatigue failure of bolted joints. Different values of frictional coefficients ...
