【摘要】：隨著世界清潔能源市場(chǎng)的快速發(fā)展,風(fēng)能作為無污染、可再生的新能源逐漸成為人們關(guān)注和利用的焦點(diǎn)。風(fēng)力發(fā)電機(jī)齒輪箱作為一個(gè)重要的機(jī)械傳動(dòng)部件,隨著風(fēng)力發(fā)電機(jī)組的逐漸大型化,維護(hù)成本的逐漸提高,對(duì)齒輪箱系統(tǒng)的穩(wěn)定性要求也越來越高。由于風(fēng)力的隨機(jī)性特點(diǎn),葉片對(duì)齒輪箱隨機(jī)性載荷的作用引起了齒輪箱系統(tǒng)的振動(dòng),這些振動(dòng)導(dǎo)致了齒輪箱傳動(dòng)系統(tǒng)的疲勞損壞,降低了齒輪箱系統(tǒng)的穩(wěn)定性,增加了維護(hù)成本。為了減少由振動(dòng)引起的齒輪箱系統(tǒng)的故障,提高系統(tǒng)的穩(wěn)定性,需要對(duì)齒輪箱傳動(dòng)系統(tǒng)進(jìn)行動(dòng)力學(xué)研究。 本文介紹了大型風(fēng)力發(fā)電機(jī)齒輪箱動(dòng)力學(xué)分析的研究發(fā)展?fàn)顩r和科學(xué)重要性。風(fēng)力發(fā)電機(jī)齒輪箱在運(yùn)行過程中受到動(dòng)態(tài)載荷的作用而產(chǎn)生振動(dòng),引起內(nèi)部構(gòu)件的疲勞損壞。討論了建立齒輪箱系統(tǒng)動(dòng)力學(xué)模型的關(guān)鍵性問題,將風(fēng)力發(fā)電機(jī)齒輪傳動(dòng)系統(tǒng)分解為三級(jí)傳動(dòng)系統(tǒng),分別為第一級(jí)的行星齒輪傳動(dòng)系統(tǒng)、第二、三級(jí)的斜齒圓柱齒輪傳動(dòng)系統(tǒng)和軸系三個(gè)部分,采用集中參數(shù)法,綜合考慮了齒輪的時(shí)變的綜合嚙合剛度、綜合嚙合誤差、橫向彎曲振動(dòng)、扭轉(zhuǎn)振動(dòng)、軸向振動(dòng)等因素的共同作用,建立了行星齒輪、斜齒圓柱齒輪和軸系的動(dòng)力學(xué)模型,從而得到整體齒輪傳動(dòng)系統(tǒng)的動(dòng)力學(xué)模型,建立了齒輪箱系統(tǒng)的動(dòng)力學(xué)微分方程,在此基礎(chǔ)上,利用振動(dòng)方程的解耦理論,對(duì)微分方程采用解析法進(jìn)行求解,同時(shí)采用四階龍格一庫塔公式的數(shù)值方法,對(duì)動(dòng)力學(xué)微分方程進(jìn)行了求解,并對(duì)齒輪傳動(dòng)系統(tǒng)進(jìn)行模態(tài)分析,得出了系統(tǒng)的固有頻率、振型等系統(tǒng)的模態(tài)參數(shù)；此外,利用系統(tǒng)的動(dòng)態(tài)激勵(lì),求解系統(tǒng)的微分方程,揭示了系統(tǒng)的動(dòng)態(tài)響應(yīng)。
[Abstract]:With the rapid development of the world market for clean energy, wind energy is a non polluting, renewable energy has gradually become the focus of attention and use. As one of the most important mechanical parts of wind turbine gearbox, as wind turbines become larger and the maintenance cost is gradually increased. The stability requirements of gear box system is also getting the higher the wind. Because of the random characters, effects of leaves on the gear box of the randomness of the load caused by the vibration of gear system, the vibration causes fatigue damage in the gear box transmission system, reducing the stability of gearbox system, increase the maintenance cost. In order to reduce the fault of gearbox system caused by vibration. To improve the stability of the system, the need for dynamic analysis of the gear transmission system.
This paper introduces the dynamic analysis of large wind turbine gearbox development and scientific importance. The wind turbine gearbox under dynamic loads during operation and vibration, fatigue damage caused by internal components. Discusses the key problems of dynamic model of gear box, the gear transmission system of wind power generator for decomposition three transmission system, respectively, planetary gear transmission system for the first grade, second, third grade helical cylindrical gear transmission system and the system of three parts, using the lumped parameter method, considering the comprehensive gear time-varying stiffness and meshing error, lateral bending vibration, torsional vibration, axial vibration interaction etc. the factors, established the dynamics model of planetary gear, helical gear and shaft, so as to get the whole power gear transmission system model is built The dynamic differential equations of gear box system, on this basis, using the decoupling theory of vibration equation, by solving the differential equation with analytical method, numerical method using four order Runge Kutta formula, the dynamic differential equations were solved, and the gear transmission system modal analysis, obtained the inherent the system frequency, mode of vibration modal parameters of the system; in addition, the use of dynamic incentive system, solving the differential equation system, reveals the dynamic response of the system.
