【摘要】：行星齒輪傳動由于具有高扭矩、傳動比大，高可靠性、高平穩(wěn)性和高傳動效率等優(yōu)點,被廣泛應(yīng)用于汽車、航空、船舶、風(fēng)力發(fā)電機(jī)、重型機(jī)械等各個傳動領(lǐng)域，但是系統(tǒng)的振動會引起噪聲和過大的動載荷，導(dǎo)致設(shè)備的過早失效，引起了國內(nèi)外學(xué)者的廣泛關(guān)注。 風(fēng)電增速齒輪箱采用了多級行星傳動方式，是風(fēng)力發(fā)電機(jī)的重要組成部分，也是整個傳動系統(tǒng)中故障率最高。研究風(fēng)電齒輪箱動力學(xué)特性，減少風(fēng)電齒輪箱齒輪傳動系統(tǒng)的沖擊和使用壽命不足成為了整個風(fēng)電行業(yè)的重要課題。本文在機(jī)械傳動國家重點實驗室自主研究課題資助下，以某1500KW風(fēng)電齒輪箱為研究對象，，建立了其剛體動力模型，進(jìn)行了在裝配誤差、制造誤差等常見誤差激勵下的多級行星傳動動力學(xué)特性研究，有一定的學(xué)術(shù)意義和實用價值。 首先，利用三維建模軟件CATIA，建立了完整的風(fēng)電齒輪箱實體模型。 其次，從理論上探討了風(fēng)電齒輪箱傳動系統(tǒng)內(nèi)部激勵和外部激勵產(chǎn)生的主要原因，建立了基于ADAMS的多體動力學(xué)模型,仿真了齒輪傳動過程中的各級齒輪嚙合力的情況，并對風(fēng)電齒輪箱前兩級行星傳動系統(tǒng)的均載特性進(jìn)行了對比。 考慮到風(fēng)機(jī)的工作環(huán)境非常惡劣，其所受外力多變，尤其在風(fēng)速突變的時候，沖擊載荷對風(fēng)機(jī)影響很大；此外受工藝水平的影響，傳動軸在加工過程中經(jīng)常會出現(xiàn)偏心等加工誤差現(xiàn)象。針對這些情況，本文對齒輪箱在受到?jīng)_擊載荷的情況下進(jìn)行了模擬，同時對高速輸出軸偏心狀況下的沖擊受力進(jìn)行了模擬，為風(fēng)電齒輪箱的設(shè)計提供了參考價值。 進(jìn)行了風(fēng)電齒輪箱傳動系統(tǒng)的非線性三維接觸動態(tài)特性研究，實現(xiàn)了齒輪系統(tǒng)嚙合沖擊的動力學(xué)仿真，得到了齒根應(yīng)力沿齒寬方向上的分布狀況。為風(fēng)電齒輪箱的制造提供參考。 風(fēng)電齒輪箱在制造裝配過程中的誤差是不可避免的，對風(fēng)電齒輪箱的壽命和有著直接的關(guān)系。本文基于ADAMS多體動力學(xué)模型仿真了齒輪傳動系統(tǒng)在各裝配誤差作用下動載系數(shù)的變換情況，從而為風(fēng)電齒輪箱的制造、安裝提供參考價值。
[Abstract]:The planetary gear transmission has the advantages of high torque , high transmission ratio , high reliability , high stability , high transmission efficiency and the like , and is widely applied to various transmission fields such as automobiles , aviation , ships , wind power generators , heavy machinery and the like , but the vibration of the system can cause noise and excessive dynamic loads , leading to premature failure of the equipment and causing extensive attention of scholars at home and abroad . The wind power speed increasing gear box adopts multi - stage planetary transmission mode , which is an important part of wind power generator and the highest failure rate in the whole transmission system . Firstly , a full model of wind turbine gear box is established by using CATIA . Secondly , the main reasons for the internal excitation and external excitation of wind power gearbox transmission system are discussed theoretically . Based on ADAMS , a multi - body dynamics model is established , which simulates the meshing force of gears at all stages in the process of gear transmission , and compares the load - carrying characteristics of the two - stage planetary transmission system in the wind power gearbox . Considering that the working environment of the fan is very bad , the external force is changeable , especially when the wind speed is abrupt , the impact load has great influence on the fan ; moreover , the machining error caused by eccentricity during the machining process is influenced by the influence of the process level . In view of these conditions , the gear box is simulated under the condition of impact load , and the impact force on the eccentric condition of the high - speed output shaft is simulated , and the reference value is provided for the design of the wind power gearbox . In this paper , the nonlinear three - dimensional contact dynamic characteristics of wind power gear box transmission system are studied . The dynamic simulation of meshing impact of gear system is realized , and the distribution of tooth root stress in the tooth width direction is obtained . It provides a reference for the manufacture of wind power gearbox . The error of wind power gear box during manufacturing and assembly process is inevitable , it has direct relation to the life of wind power gear box . Based on ADAMS multi - body dynamics model , the transformation of dynamic load factor of gear transmission system under each assembly error is simulated , which provides reference value for the manufacture and installation of wind power gear box .
