A Novel Mooring Tether for Highly-Dynamic Offshore Applications; Mitigating Peak and Fatigue Loads via Selectable Axial Stiffness

open access: yesJournal of Marine Science and Engineering, 2015
Highly-dynamic floating bodies such as wave energy convertors require mooring lines with particular mechanical properties; the mooring system must achieve adequate station keeping whilst controlling mooring tensions within acceptable limits.

Surrogate Models for Wind Turbine Electrical Power and Fatigue Loads in Wind Farm

open access: yesEnergies, 2020
Fatigue damage of turbine components is typically computed by running a rain-flow counting algorithm on the load signals of the components. This process is not linear and time consuming, thus, it is non-trivial for an application of wind farm control ...

A 2.5MW Wind Turbine TL-EMPC Yaw Strategy Based on Ideal Wind Measurement By LiDAR

open access: yesIEEE Access, 2021
This paper analyzes the yaw data of the 2.5MW wind turbine of XEMC Windpower Company, and the real wind information collected by the wind farm, and proposes a two-level economic model predictive control (TL-EMPC) yaw strategy based on ideal wind ...

Fatigue loading of tendon

open access: yesInternational Journal of Experimental Pathology, 2013
SummaryTendon injuries, often called tendinopathies, are debilitating and painful conditions, generally considered to develop as a result of tendon overuse. The aetiology of tendinopathy remains poorly understood, and whilst tendon biopsies have provided some information concerning tendon appearance in late‐stage disease, there is still little ...

Active Disturbance Rejection Control for Wind Turbine Fatigue Load

open access: yesEnergies, 2022
With the participation of wind power in grid frequency modulation, the fatigue load of the wind turbine increases accordingly. A new control method that considers both fatigue load and output power of wind turbine (WT) is proposed in this paper. A linear

Fracture behavior of low cycle fatigue and dwell fatigue of Ti6242 titanium alloy under high load

open access: yesJournal of Aeronautical Materials, 2019
As one kind of near alpha titanium alloys with excellent mechanical properties, Ti6242 alloy always shows the“dwell fatigue”characteristic, which is similar to other near α or α+β titanium alloys, especially at near room temperature.

Numerical analysis of fatigue behaviors for tungsten armor of ITER divertor

open access: yesNuclear Materials and Energy, 2020
Thermal responses and fatigue behaviors of the tungsten armor of monoblock divertor under steady-state and transient high heat flux (HHF) loads as well as the coupling of the two were simulated and analyzed by the finite element method. It was found that,

The kinematics of loading and fatigue in the Standardbred trotter [PDF]

open access: yesEquine Veterinary Journal, 1999
Summary The Standardbred trotter must pull a considerable load when racing and, consequently, draught loading is a common method of training in the Standardbred and the effects of loading and fatigue due to loading on the locomotor pattern was the purpose of this investigation.

Fatigue and Training Load Factors in Volleyball

open access: yesInternational Journal of Environmental Research and Public Health, 2022
The purpose of this article was to determine the internal and external loads experienced by volleyball players in a weekly cycle during the competitive season. Using accelerometers, as well as subjective rating perceived exertion (RPE) and total quality recovery scale (TQR) questionnaires, eleven female athletes were monitored during five days of ...
