【摘要】:化石燃料的日益枯竭,開(kāi)發(fā)新能源刻不容緩。風(fēng)能作為一種開(kāi)發(fā)較早,技術(shù)比較成熟的清潔能源,得到了較好的發(fā)展,其中離岸風(fēng)力發(fā)電作為目前比較熱門(mén)的風(fēng)力發(fā)電技術(shù)得到了較多的關(guān)注,通過(guò)對(duì)離岸型風(fēng)力發(fā)電機(jī)的疲勞壽命進(jìn)行深入研究,對(duì)于提高我國(guó)自主離岸風(fēng)電技術(shù),降低對(duì)國(guó)外企業(yè)技術(shù)的依賴,打破西方壟斷起到重要意義。本研究對(duì)一種常用型號(hào)的離岸風(fēng)力發(fā)電機(jī)(WT_86),通過(guò)綜合應(yīng)用3D CAD/CAE軟件對(duì)風(fēng)機(jī)進(jìn)行了其在正常工作以及異常風(fēng)況條件下的的結(jié)構(gòu)疲勞壽命分析,對(duì)其在不同工作狀態(tài)下的壽命進(jìn)行了分析和預(yù)測(cè),為此型風(fēng)機(jī)的改進(jìn)提供的重要依據(jù)。WT_86型2MW風(fēng)力發(fā)電機(jī)是目前比較常用的一種離岸風(fēng)機(jī)型號(hào)。本文通過(guò)SolidWorks軟件對(duì)風(fēng)機(jī)的輪轂、機(jī)艙、塔柱進(jìn)行了模型的建立,通過(guò)ANSYS ACP/APDL對(duì)風(fēng)機(jī)葉片進(jìn)行了精細(xì)的復(fù)合材料建模,之后再選用Fluent軟件,選用標(biāo)準(zhǔn)K-epsilon湍流模型,對(duì)風(fēng)機(jī)進(jìn)行了流體分析,之后通過(guò)Static Structural對(duì)風(fēng)機(jī)進(jìn)行了靜態(tài)分析,驗(yàn)證了其結(jié)構(gòu)安全,之后通過(guò)匯入Fluent得到的分析數(shù)據(jù)進(jìn)入Static Structural進(jìn)行了流固耦合分析以及通過(guò)Fatigue Tools進(jìn)行了疲勞壽命分析,驗(yàn)證了其疲勞壽命達(dá)到了預(yù)計(jì)的設(shè)計(jì)壽命。
[Abstract]:With the increasing depletion of fossil fuels, it is urgent to develop new energy sources. Wind energy, as a kind of clean energy developed earlier and more mature in technology, has got better development, among which offshore wind power generation has been paid more attention as a popular wind power generation technology at present. By studying the fatigue life of offshore wind turbine, it is of great significance to improve the offshore wind power technology in China, reduce the dependence on foreign enterprises and break the western monopoly. In this study, the structural fatigue life of a commonly used offshore wind turbine, WT86T, was analyzed under normal and abnormal wind conditions by using 3D CAD/CAE software. The life of the wind turbine in different working conditions is analyzed and forecasted, and the important basis for the improvement of this type of fan. WTS / 86 2MW wind turbine is a commonly used offshore fan model at present. In this paper, the model of the wheel hub, engine room and tower column of the fan is established by SolidWorks software, and the fine composite modeling of the fan blade is carried out by ANSYS ACP/APDL, then the Fluent software and the standard K-epsilon turbulence model are selected. The flow analysis of the fan is carried out, and the static analysis of the fan is carried out through Static Structural, which verifies its structural safety. After that, the analysis data from Fluent are imported into Static Structural for fluid-solid coupling analysis and Fatigue Tools for fatigue life analysis. It is verified that its fatigue life has reached the expected design life.
