The main drivetrain system‘s modeling and simulation of wind generators are operated on the SolidWorks software platform. The modeling of the round wheel, axle, gear boxes, electrical, cabin chassis of the wind generator is conducted on this article. The main ponents in the drivetrain system on the role of wind power generation units were introduced, and the selection of its form and structure of a detailed analysed. Wind generators’ operating environment is very bad, the various ponents of its main drivetrain system were introduced in the selection of materials. To ensure that wind generators in their normal life, the intensity analysis of the main axle is conducted. For the gear boxes in wind generators have special role for the transmission gear box form types, characteristics and applications were introduced, and its reasonable selection. According to gear boxes growth, a reasonable choice of gear wheel axle and gear box at all levels of the parameters is conducted. Wind generators’ generator is one of the important part, it will wind round the mechanical energy into electrical energy. The selection of generators is particularly important, therefore, to the choice of this doublefed asynchronous generator work and the role of theory was introduced. Because of the drivetrain system installation requirements, the modeling of the cabin chassis, and strength and rigidity to meet the premise of its material and shape a reasonable choice was introduced. Finally, All the parts and ponents designed on the SolidWorks platform drivetrain are assembled, and the transmission simulation display is also conducted, allowing a more intuitive understanding of the wind generator drivetrain system and the position of the work. Key words: Wind generators； The drivetrain system； Modeling； Simulation IV 目 錄 摘 要 .............................................................I ABSTRACT .........................................................III 第 1 章 引 言 .....................................................1 課題的背景及意義 .............................................1 目前國內(nèi)外風(fēng)力機(jī)組發(fā)展現(xiàn)狀 ...................................1 國外發(fā)展現(xiàn)狀 .............................................1 國內(nèi)發(fā)展現(xiàn)狀 .............................................2 課題所要解決的問題 ...........................................2 第 2 章 風(fēng)機(jī)主傳動系統(tǒng)的總體設(shè)計(jì) ...................................3 風(fēng)力發(fā)電機(jī)主傳動系統(tǒng)的組成 ...................................3 風(fēng)力發(fā)電機(jī)主傳動系統(tǒng)的工作原理 ...............................3 風(fēng)力發(fā)電機(jī)主傳動系統(tǒng)的布置形式 ...............................3 第 3 章 風(fēng)機(jī)主傳動系統(tǒng)中主要部件設(shè)計(jì) ...............................5 輪轂的形式與選用 .............................................5 輪轂的作用及結(jié)構(gòu) .........................................5 輪轂的形式 ...............................................5 主軸的設(shè)計(jì) ...................................................6 主軸的作用及結(jié)構(gòu) .........................................6 主軸強(qiáng)度校核 .............................................6 主軸材料 .................................................8 齒輪箱的構(gòu)造及選用 ...........................................8 齒輪箱的構(gòu)造 .............................................8 齒輪箱的箱體設(shè)計(jì) ........................................11 齒輪箱的齒輪設(shè)計(jì) ........................................11 齒輪箱軸的設(shè)計(jì) ..........................................13 V 齒輪箱的軸承設(shè)計(jì) ........................................13 電機(jī)的選用 ..................................................14 電機(jī)選用 ................................................14 雙饋異步電機(jī)的工作原理 ..................................14 機(jī)艙底盤作用及選用 ..........................................15 機(jī)艙底盤的分類及選用 ....................................15 機(jī)艙底盤設(shè)計(jì)要求 .......................................
