Analysis of Wind-Turbine Steel Tower by Transfer Matrix

Abstract

A new method is put forward for analysis bending deflection of the wind-turbine steel tower based on transfer matrix method. The steel tower of wind-turbine structure is simplified as a beam-column with varying diameter involve in bending and torsion. The transfer matrix is obtained by solution of the differential equations of beam-column subject to an axial force and other complex loads in 2-dimension. One exist steel tower is analyzed by this method for example, and the on-plane deformation was calculated by the present method. The results show that transfer matrix method is reliability and accuracy, which can meet the requirement of wind turbine engineering structure, and it is effective to solve the problems of the wind-turbine tower, especially for the case with additional bending moments caused by compressive force.

Dynamic Analysis on Pile Group Supported Offshore Wind Turbine under Wind and Wave Load

“…By using the transfer matrix method [21][22][23], the dynamic response of different pile parts can be connected. Wang [24] analyzed the onshore wind turbine structure natural frequency using the transfer matrix method. Huang [25] analyzed the dynamic response of the pile group supported OWT using the transfer matrix method.…”

Vibration analysis system applied to fault detection in wind turbines

“…Considering the traditional predictive techniques, those based on vibration analysis are the most commonly used, allowing to know the status of the equipment and control their availability (Wang et al, 2009). Hence, there is diverse equipment available that perform vibration analysis in wind turbines, such as: Analyzer Pro 2130, SFK Preditec Analyzer CMVA 65, Pruftechnik VIBNODE, IDEAR Vibraspec.…”
