Corrosion Protection Design of Support Structures for Offshore Wind Turbines with Analysis of Material Properties Bixiang Mei 1, a 1Department of Civil Engineering,Nangchang Institute of Technology, 289 Tianxiang Road, Nanchang 330099, China aemail:809622645@qq.com Key words: offshore wind turbines; support structures; corrosion protection；material properties Abstract: The paper provides a review about the corrosion ,corrosion protection and material properties of support structures for offshore wind turbines.
On the other hand, the support structure of offshore wind turbines can not be repaired easily once corroded due to its special geographical environment and technical requirements, and the maintenance cost is very expensive[1].Therefore, it is very significant in engineering practice to research the corrosion protection measures of the support structure of offshore wind turbines. 2 Current state of corrosion protection research on offshore wind turbines Systematic significant investigations into the corrosion protection of offshore wind turbines are just a few.
(4) Sea bed zone Steel structures in the sea bed zone are normally cathodically protected. 4.2 Corrosion protection measures for reinforced concrete 1) Concrete surface coating Concrete surface coating is one of special protective measures of concrete structure durability in offshore engineering.
The design life of coating system should not be less than 10a. 2) Concrete surface silane impregnation Concrete structure in offshore engineering is exposed to harsh environment where chloride has intruded.
Silane impregnation is suitable for the corrosion protection for concrete structure in splash zone of offshore engineering, and isobutene triethoxysilane should be used as silane impregnation materials.Other silane impregnation materials can be used by the arguments. 3) Epoxy coating rebar The measure of epoxy coating rebar is suitable for splash zone and intermediate zone in concrete structure of offshore engineering.

Introduction Vibration is nature and engineering common phenomenon.
Although there are many engineering of vibration of equipment and technology, but usually vibration on system itself and the environment is harmful, and it directly influence the instrument equipment function, reduce the safety and reliability of the mechanical facilities.
So, for most of the machine equipment and engineering structure, it will generally ask the possible vibration magnitude control within a certain range.
Vibration control is the vibration absorber , away, and vibration damping technology measures to reduce machine equipment and engineering structure vibration and stop its spread, the vibration control mechanism according to the different control can be divided into passive and active control two kinds big.
Especially with the information technology, the development of the measurement and control technology, some control method and the corresponding measurement and control system matures, promote the active vibration control technology progress, and start in aerospace, civil construction, vehicle engineering and mechanical engineering fields successful applications.
