【摘要】：隨著石油、煤炭等常規(guī)能源的日益枯竭,風(fēng)能資源以其獨特的優(yōu)勢越來越受到廣大人們的關(guān)注,風(fēng)電產(chǎn)業(yè)在未來能源戰(zhàn)略中將占據(jù)至關(guān)重要的地位。風(fēng)電增速箱是風(fēng)電系統(tǒng)的關(guān)鍵部件,其設(shè)計制造技術(shù)在很大程度上制約著發(fā)電能力。本文在研究超環(huán)面行星蝸桿傳動理論的基礎(chǔ)上,將超環(huán)面行星蝸桿傳動理論引入風(fēng)力發(fā)電領(lǐng)域,設(shè)計一種新型的兆瓦級風(fēng)力發(fā)電增速器——兆瓦級風(fēng)力發(fā)電滾錐齒超環(huán)面行星蝸桿增速器,以促進大功率風(fēng)力發(fā)電機組的快速發(fā)展的目的。主要研究的內(nèi)容如下: 開展了超環(huán)面行星蝸桿傳動的空間嚙合理論的研究,針對兆瓦級大功率動力傳動要求,設(shè)計了兆瓦級風(fēng)力發(fā)電滾錐齒超環(huán)面行星蝸桿增速器的結(jié)構(gòu)方案,主要包括傳動的核心部分、支撐部分、潤滑系統(tǒng)和冷卻裝置的設(shè)計。 綜合運用改進的遺傳算法IP_μGA (a modified micro genetic algorithm with the strategy of Intergeneration Projection)和外懲罰函數(shù)法開展了兆瓦級風(fēng)力發(fā)電滾錐齒超環(huán)面行星蝸桿增速器的主要性能參數(shù)優(yōu)化設(shè)計。 綜合運用響應(yīng)面法、有限元分析技術(shù)及正交試驗設(shè)計方法,開展了增速器的結(jié)構(gòu)參數(shù)的優(yōu)化設(shè)計。運用正交試驗設(shè)計方法來安排有限元分析方案,提取相應(yīng)的計算結(jié)果,將得到的數(shù)據(jù)使用響應(yīng)面法來建立一個設(shè)計變量與目標函數(shù)之間的對應(yīng)關(guān)系。將該對應(yīng)關(guān)系可視化顯示為曲線圖,通過人工調(diào)整曲線圖中設(shè)計變量的取值范圍來求得增速器結(jié)構(gòu)參數(shù)的最優(yōu)解。 最后,基于UG二次開發(fā)技術(shù)構(gòu)建了滾錐齒超環(huán)面行星蝸桿增速器的設(shè)計平臺的基本框架,向用戶提供了與UG系統(tǒng)風(fēng)格相似的可視化設(shè)計環(huán)境。將前述性能參數(shù)優(yōu)化設(shè)計嵌入到框架中,實現(xiàn)了預(yù)期的功能。通過參數(shù)化建模,以UG作為二次開發(fā)平臺,對增速器零部件進行二次開發(fā),減少花費在重復(fù)性工作上的時間,從而大大地提高了設(shè)計效率。
[Abstract]:With the increasing depletion of conventional energy such as petroleum coal and so on wind energy resources have attracted more and more attention due to their unique advantages. Wind power industry will play an important role in the future energy strategy. Wind power booster is the key component of wind power system, and its design and manufacture technology restricts the power generation ability to a great extent. On the basis of studying the theory of supertoroidal planetary worm drive, this paper introduces the theory of hypertoroidal planetary worm drive into the field of wind power generation. In order to promote the rapid development of high power wind turbine, a new type of megawatt wind turbine is designed, which is called megawatt wind turbine supertoroidal planetary worm governor. The main research contents are as follows: the space meshing theory of supertoroidal planetary worm drive is studied, aiming at the requirements of megawatt power transmission, The structure scheme of megawatt wind power generation supertoroidal planetary worm governor is designed, which mainly includes the core part of transmission, the support part, the lubrication system and the design of cooling device. Based on the improved genetic algorithm (IP_ 渭 GA (a modified micro genetic algorithm with the strategy of Intergeneration Projection) and the external penalty function method, the optimization design of the main performance parameters of the supertoroidal planetary worm governor with bevel teeth in MW level wind power generation has been carried out by using the improved genetic algorithm, 渭 GA (a modified micro genetic algorithm with the strategy of Intergeneration Projection) and external penalty function method. Using the response surface method, finite element analysis technique and orthogonal test design method, the optimization design of structural parameters of the governor is carried out. The orthogonal experiment design method is used to arrange the finite element analysis scheme, and the corresponding calculation results are extracted. The response surface method is used to establish a corresponding relationship between the design variable and the objective function. The corresponding relation is visualized as a graph and the optimal solution of the structural parameters of the governor is obtained by manually adjusting the range of the design variables in the graph. Finally, based on the secondary development technology of UG, the basic framework of the design platform of the spiral gear booster with bevel tooth hypertorus is constructed, which provides users with a visual design environment similar to the style of the UG system. The above performance parameter optimization design is embedded in the framework to achieve the desired function. By using parameterized modeling and taking UG as the secondary development platform, the time spent on repetitive work is reduced, and the design efficiency is greatly improved.
