In marine diesel engine, main bearing bolts (M18×1.5) withstand large tensile and cyclic loads to keep the crank shaft, bearing whit acceptable clearance and precision clamping force at high crank speed like 3100 rpm. In this research, the relationship between torque and clamp force, the friction coefficient, the effect of number of tightening and bearing conditions on the new manufactured bolt...

An Intelligent Fixturing System (IFS) is currently being developed to hold a family of thin-walled workpieces for machining operations. This is a cost-effective system which uses off-line optimisation of the clamps location and on-line adjustment of clamping forces. As adaptive clamping forces appropriate to the dynamic machining environment are employed, the IFS offers higher quality of machin...

The handle of a commercial bar clamp was redesigned using ergonomic principles and then compared with an original clamp. Ten male and ten female students participated in simulated clamping tasks under various conditions, including different clamping heights, clamping methods, and handle-gripping methods, with respect to the dependent variables of clamping and handle-squeezing forces. The result...

This paper proposes a sensor-less robust force control method for improving the control performance of an electro-mechanical brake (EMB) which is applicable to commercial city buses. The EMB generates the accurate clamping force commanded by a driver through an independent motor control at each wheel instead of using existing mechanical components. In general, an EMB undergoes parameter variati...
