根據2.5MW風力發電機行星齒輪驅(qu)動(dong)(dong)系(xi)(xi)統(tong)(tong)在隨(sui)機(ji)風(feng)場(chang)中復(fu)雜工(gong)況的工(gong)作特(te)點，利用(yong)雙參數威(wei)布爾分布模(mo)型(xing)(xing)描述隨(sui)機(ji)風(feng)速的分布，獲得由隨(sui)機(ji)風(feng)速引起的時(shi)變(bian)風(feng)載(zai)。采用(yong)集中參數法建立風(feng)力發(fa)電(dian)機(ji)行(xing)(xing)(xing)星(xing)(xing)齒輪驅(qu)動(dong)(dong)系(xi)(xi)統(tong)(tong)平移(yi)-扭轉耦合(he)動(dong)(dong)力學模(mo)型(xing)(xing)。綜合(he)考慮風(feng)力發(fa)電(dian)機(ji)行(xing)(xing)(xing)星(xing)(xing)齒輪驅(qu)動(dong)(dong)系(xi)(xi)統(tong)(tong)的軸(zhou)承支(zhi)撐剛(gang)度(du)、齒輪副時(shi)變(bian)嚙合(he)剛(gang)度(du)等(deng)內部激勵對驅(qu)動(dong)(dong)系(xi)(xi)統(tong)(tong)的影響，對變(bian)風(feng)載(zai)下2.5MW行(xing)(xing)(xing)星(xing)(xing)齒輪驅(qu)動(dong)(dong)系(xi)(xi)統(tong)(tong)的動(dong)(dong)力學特(te)性進行(xing)(xing)(xing)仿真計算分析(xi)，求得出載(zai)外部風(feng)載(zai)作用(yong)下各構(gou)件的位移(yi)響應(ying)(ying)與速度(du)響應(ying)(ying)，為(wei)風(feng)力發(fa)電(dian)機(ji)行(xing)(xing)(xing)星(xing)(xing)齒輪驅(qu)動(dong)(dong)系(xi)(xi)統(tong)(tong)的故障診斷和優化設計奠定了良(liang)好的理論基(ji)礎(chu)。

  風(feng)力發電(dian)(dian)機(ji)行星(xing)齒輪(lun)驅動(dong)系統(tong)(tong)是(shi)風(feng)力發電(dian)(dian)機(ji)的(de)(de)關鍵部件，由于其所受的(de)(de)外(wai)部載荷(he)具有時變(bian)特性，且工作環(huan)境在(zai)空架(jia)設的(de)(de)機(ji)艙(cang)中，不便于實時監控及檢測，另外(wai)在(zai)運行過程(cheng)中產生的(de)(de)振動(dong)和噪(zao)音是(shi)不可的(de)(de)這使(shi)得更為準(zhun)確的(de)(de)研究齒輪(lun)箱驅動(dong)系統(tong)(tong)動(dong)力學特性變(bian)的(de)(de)越來越重要。
