【摘要】：能源作為社會(huì)存在和發(fā)展的堅(jiān)實(shí)基礎(chǔ),是經(jīng)濟(jì)增長(zhǎng)和社會(huì)進(jìn)步的重要保證。由于常規(guī)能源造成的能源短缺和環(huán)境污染等問題日益嚴(yán)重,為了解決這些問題,以確保各種經(jīng)濟(jì)領(lǐng)域的正常運(yùn)行,實(shí)現(xiàn)經(jīng)濟(jì)和社會(huì)可持續(xù)發(fā)展,世界各國(guó)紛紛開始調(diào)整能源結(jié)構(gòu),大力開發(fā)新能源。風(fēng)能作為一種可再生、干凈無污染的能源被世界各國(guó)所關(guān)注。 風(fēng)電齒輪箱作為風(fēng)電機(jī)組的核心組成部分之一,其齒輪系統(tǒng)的振動(dòng)、噪聲等問題影響著風(fēng)電機(jī)組的正常運(yùn)轉(zhuǎn),因此研究風(fēng)電齒輪箱的動(dòng)態(tài)特性對(duì)于提高風(fēng)電機(jī)組的整體壽命具有重要的意義。本文運(yùn)用虛擬樣機(jī)技術(shù)對(duì)1.5MW風(fēng)電齒輪箱的動(dòng)態(tài)特性進(jìn)行分析研究,主要內(nèi)容如下： 確定了1.5MW風(fēng)電齒輪箱的傳動(dòng)結(jié)構(gòu),給出了齒輪箱的各個(gè)部件設(shè)計(jì)參數(shù),同時(shí)對(duì)關(guān)鍵零部件進(jìn)行了強(qiáng)度校核。利用Pro/E建立風(fēng)電齒輪箱的各個(gè)零件模型,并得到裝配體。 基于計(jì)算多體系統(tǒng)動(dòng)力學(xué)理論,對(duì)多體系統(tǒng)動(dòng)力學(xué)建模理論、計(jì)算方法和求解過程進(jìn)行了討論。在ADAMS中建立了風(fēng)電齒輪箱的多體系統(tǒng)動(dòng)力學(xué)模型。 在ADAMS中建立風(fēng)電齒輪箱的虛擬樣機(jī),計(jì)算并設(shè)置仿真所需要的參數(shù)；對(duì)仿真結(jié)果進(jìn)行分析和討論,并且與理論計(jì)算結(jié)果進(jìn)行對(duì)比,證明了仿真結(jié)果的正確性。 以風(fēng)電齒輪箱中速級(jí)為對(duì)象對(duì)行星輪系進(jìn)行了受力分析,將行星架和行星輪之間原有的旋轉(zhuǎn)副用柔性襯套(bushing)代替,以此來模擬軸承獲得更多的動(dòng)態(tài)特性,得到了與理論結(jié)果相吻合的仿真結(jié)果。 采用大型有限元分析軟件ANSYS對(duì)齒輪箱中速級(jí)的行星輪、太陽(yáng)輪、齒圈進(jìn)行了柔性化處理,生成了模態(tài)中性文件(MNF),并用這些柔性化的零件代替原來的剛性體。對(duì)齒輪箱進(jìn)行了剛?cè)狁詈戏抡?得到了柔性體的動(dòng)態(tài)應(yīng)力應(yīng)變、最大應(yīng)力位置、危險(xiǎn)節(jié)點(diǎn)等信息。
[Abstract]:As a solid foundation of social existence and development, energy is an important guarantee of economic growth and social progress. As a result of the growing problems of energy shortages and environmental pollution caused by conventional energy, in order to address these problems in order to ensure the normal functioning of various economic fields and to achieve sustainable economic and social development, Countries around the world have begun to adjust the energy structure, vigorously develop new energy. As a kind of renewable, clean and clean energy, wind energy is concerned by all countries all over the world. As one of the core components of wind turbine, the vibration and noise of its gear system affect the normal operation of wind turbine. Therefore, it is important to study the dynamic characteristics of wind turbine gearbox to improve the whole life of wind turbine. In this paper, the dynamic characteristics of 1.5MW wind power gearbox are analyzed by virtual prototyping technology. The main contents are as follows: The transmission structure of 1.5MW wind power gearbox is determined, the design parameters of each part of the gearbox are given, and the strength of key parts is checked. Each part model of wind power gearbox is established by Pro/E, and the assembly is obtained. Based on the theory of computational multi-body system dynamics, the modeling theory, calculation method and solution process of multi-body system dynamics are discussed. The multi-body system dynamics model of wind power gearbox is established in ADAMS. The virtual prototype of wind power gearbox is built in ADAMS, the parameters needed for simulation are calculated and set, the simulation results are analyzed and discussed, and compared with the theoretical results, the correctness of the simulation results is proved. Taking the mid-speed stage of the wind power gearbox as the object, the force of the planetary gear train is analyzed, and the original rotating pair between the planetary frame and the planetary gear is replaced by flexible bushinging, so as to simulate the bearing to obtain more dynamic characteristics. The simulation results are in agreement with the theoretical results. In this paper, a large finite element analysis software (ANSYS) is used to flexible the planetary gear, solar wheel and gear ring of the gear box. The modal neutral file is generated, and the original rigid body is replaced by these flexible parts. The rigid-flexible coupling simulation of the gearbox is carried out, and the dynamic stress-strain, maximum stress position and dangerous nodes of the flexible body are obtained.
