All rotating equipment power trains found in a power plant have some amount of vibration, usually caused by mechanical unbalance of the rotating system, shaft misalignment, or weakness in the bearing ...

Mechanical damping of the turbine generator (T-G) is higher at higher power level. Subsynchronous torsional interaction (SSTI) depends on the degree of coupling between the HVDC converter and the T-G, ...

Lasers have been routinely employed to cool down atomic gases since the 1980s, and have been used in the linear motion of nanoscale mechanical oscillators since around 2010. The new paper presents the ...

A major advantage of atomic force microscopes (AFMs) is their versatility in integrating various operational modes that assess different material properties and functionalities. Among the most ...

A new advance in vibration monitoring, developed with EPRI, facilitates the measurement of torsional vibration and is expected to be of significant value to power plants relying on a wide range of ...

This paper was first presented at the Gas Machinery Research Council 2021 Gas Machinery Conference in Louisville, Kentucky in October 2021. Because of the original length of the paper, it has been ...

Background Football turf is increasingly used in European soccer competition. Little is known on the rotational torque that players experience on these fields. High rotational torques between the shoe ...
