Study on vibration control of cables with elastic end restraint(II):Experimental verification
The experimental research is conducted to study the axial passive control of cable vibration by setting an elastic end restraint at one support of the cable in the axial direction.The influence of support motion on the natural frequency of cable vibration is presented.Then the damping effect of elastic restraint is verified and the influence of the damping coefficient and the spring stiffness on the damping effect is discussed.Finally the theoretical study [10] is verified to be accurate.
Abstract Wind is one of the fastest-growing renewable sources of electricity. As with most renewables, the economic viability relies on public subsidies. Even among renewables, the economic evaluation of wind projects is particularly challenging due to the unpredictability of the energy source, wind, and the high sensitivity of the project profitability to changes in a number of parameters. This makes the uncertainty analysis an important topic of research in the wind power sector. This study presents a method of combining two uncertainty analysis methods, sensitivity study and the Monte Carlo method, together with a technical and economic model of a wind farm, in an effort to improve the understanding of the practical effects of the uncertainties, and how they affect the financial risks of wind projects.
