【摘要】：近年來,風力發(fā)電產(chǎn)業(yè)在世界范圍內(nèi)得到快速發(fā)展,兆瓦級風電機組已成為我國風電市場的主流產(chǎn)品。工作環(huán)境的特殊性,對風電機組關(guān)鍵部件(如增速、變槳、偏航系統(tǒng)等)的可靠性和使用壽命提出了很高要求。因此,開展風電增速齒輪傳動系統(tǒng)的動態(tài)設(shè)計研究具有重要的科學意義與工程應用價值。在國家自然科學基金項目(50905122)的資助下,本文以兩級行星加一級平行軸式的兆瓦級風電增速箱為例,對該類齒輪傳動系統(tǒng)的動力學特性進行了較深入的研究,主要內(nèi)容如下: 在介紹了該類風電增速齒輪傳動系統(tǒng)的結(jié)構(gòu)組成的基礎(chǔ)上,采用集中參數(shù)法建立各級傳動的平移-扭轉(zhuǎn)耦合動力學模型。通過分析各構(gòu)件之間的相對位移關(guān)系,推導出系統(tǒng)的運動微分方程,并給出時變嚙合剛度、嚙合誤差、外部激勵及連接剛度的計算方法。 借助模態(tài)分析理論計算了該類風電增速齒輪傳動系統(tǒng)的固有頻率與振型。研究表明,上述系統(tǒng)存在三種典型的振動模式,即單級行星輪系中心構(gòu)件平移振動模式、三級齒輪傳動振動模式和平行軸齒輪振動模式。詳細分析了系統(tǒng)固有特性對其剛度參數(shù)的敏感度。 應用諧波平衡法求解了該類風電增速齒輪傳動系統(tǒng)的位移響應,揭示出內(nèi)部、外部激勵對系統(tǒng)動態(tài)響應的影響規(guī)律,并計算了各嚙合齒輪副的使用系數(shù)和動載系數(shù)。在此基礎(chǔ)上,進一步分析了改善系統(tǒng)動態(tài)響應的措施,如相位調(diào)諧、太陽輪浮動、高速級齒輪轉(zhuǎn)動慣量調(diào)整等。 上述研究成果為該類風電增速齒輪傳動系統(tǒng)的動態(tài)設(shè)計提供了理論依據(jù)。
[Abstract]:In recent years, wind power generation industry has developed rapidly in the world, and megawatt wind turbine has become the mainstream of wind power market in China. Because of the particularity of the working environment, the reliability and service life of the key components (such as speed up, propeller, yaw system, etc.) of the wind turbine are very high. Therefore, it is of great scientific significance and engineering application value to study the dynamic design of wind power acceleration gear transmission system. Supported by the National Natural Science Foundation of China (50905122), the dynamic characteristics of this kind of gear transmission system are studied in this paper with the example of two-stage planetary and one-stage parallel axis type megawatt wind power growth box. The main contents are as follows: on the basis of introducing the structure composition of the gear transmission system of this kind of wind power speed up, the coupling dynamic model of translation and torsion of all levels of transmission is established by means of the method of concentrated parameters. Based on the analysis of the relative displacement relationship between the components, the differential equations of motion of the system are derived, and the calculation methods of the time-varying meshing stiffness, meshing error, external excitation and connection stiffness are given. Based on modal analysis theory, the natural frequency and mode shape of this kind of wind power acceleration gear transmission system are calculated. The results show that there are three typical vibration modes in the system, namely, the translational vibration mode of the central component of the single-stage planetary gear train, the vibration mode of the three-stage gear transmission and the vibration mode of the parallel shaft gear. The sensitivity of the inherent characteristics of the system to its stiffness parameters is analyzed in detail. The harmonic balance method is used to solve the displacement response of this kind of wind power acceleration gear transmission system. The influence of internal and external excitation on the dynamic response of the system is revealed, and the use coefficient and dynamic load coefficient of each meshing gear pair are calculated. On this basis, the measures to improve the dynamic response of the system are further analyzed, such as phase tuning, solar wheel floating, moment of inertia adjustment of high-speed gear and so on. The above research results provide a theoretical basis for the dynamic design of the speed-increasing gear transmission system of this kind of wind power.
