On a Sensor Placement Methodology for Monitoring the Vibrations of Horizontally Excited Ground [PDF]

open access: yesSensors, 2020
In this paper, the problem of optimal sensor arrangement during vibration monitoring is analysed. The wave propagation caused by horizontal excitation is investigated to predict the areas of the largest ground and structure response. The equations of motion for a transversally isotropic elastic medium with appropriate absorbing boundary conditions are ...

The specification and testing of a Horizontal Axis Tidal Turbine Rotor Monitoring approach [PDF]

open access: yesInternational Journal of Prognostics and Health Management, 2020
The sustainable deployment of Horizontal Axis Tidal Turbines will require effective management and maintenance functions. In part, these can be supported by the engineering of suitable condition monitoring systems. The development of such a system is inevitably challenging, particularly given the present limited level of operational data associated ...
