The Ultimate Guide to Marine Shaft Power (Torsion) Meters
Power (Hp) = Torque (ft-lbs) x RPM / 5252. Power (kW) = Torque (Nm) x RPM / 9550. Because of the close relation between power and torque, the name "shaft power meter" is often used interchangeably with "shaft torque meter" or "shaft torsion meter". Both torque and power can be important values depending on the application.

Hot rolling mills suffer from severe torsional vibrations in particular working conditions (thin thickness). These vibrations are often explained as the result of an exogenous disturbance amplified by a resonance effect. In this paper, we show that these vibrations are in fact produced by the interaction between the kinematic chain and the phenomenon of the …
