由于風力發電機齒輪箱安裝(zhuang)在柔性(xing)(xing)(xing)支承(cheng)德搭(da)架(jia)(jia)上(shang)，在復雜的(de)(de)工況下風(feng)(feng)(feng)力(li)(li)(li)(li)發電機(ji)(ji)(ji)(ji)搭(da)架(jia)(jia)將產生彎曲(qu)擺(bai)動(dong)(dong)(dong)(dong)，嚴重影(ying)響著風(feng)(feng)(feng)力(li)(li)(li)(li)機(ji)(ji)(ji)(ji)齒輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)系(xi)(xi)統(tong)的(de)(de)動(dong)(dong)(dong)(dong)態(tai)特性(xing)(xing)(xing)。考慮(lv)了風(feng)(feng)(feng)力(li)(li)(li)(li)機(ji)(ji)(ji)(ji)搭(da)架(jia)(jia)的(de)(de)擺(bai)動(dong)(dong)(dong)(dong)與(yu)行(xing)星(xing)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)扭轉振(zhen)動(dong)(dong)(dong)(dong)的(de)(de)耦合(he)效應，利用集中參數法(fa)建(jian)立柔性(xing)(xing)(xing)支承(cheng)下的(de)(de)風(feng)(feng)(feng)力(li)(li)(li)(li)機(ji)(ji)(ji)(ji)行(xing)星(xing)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)系(xi)(xi)統(tong)的(de)(de)動(dong)(dong)(dong)(dong)力(li)(li)(li)(li)學分析模型(xing)，用Matlab進(jin)行(xing)數值求解。通(tong)過(guo)對1.5MW主流風(feng)(feng)(feng)力(li)(li)(li)(li)行(xing)星(xing)齒輪(lun)系(xi)(xi)統(tong)進(jin)行(xing)實例分析，得到了16s時(shi)序隨機(ji)(ji)(ji)(ji)風(feng)(feng)(feng)載(zai)下的(de)(de)行(xing)星(xing)齒輪(lun)系(xi)(xi)統(tong)各部件的(de)(de)位移歷程(cheng)。結果(guo)表明(ming)：在風(feng)(feng)(feng)力(li)(li)(li)(li)機(ji)(ji)(ji)(ji)運行(xing)中搭(da)架(jia)(jia)產生劇烈(lie)震動(dong)(dong)(dong)(dong)，風(feng)(feng)(feng)力(li)(li)(li)(li)機(ji)(ji)(ji)(ji)搭(da)架(jia)(jia)的(de)(de)震動(dong)(dong)(dong)(dong)加劇了風(feng)(feng)(feng)力(li)(li)(li)(li)機(ji)(ji)(ji)(ji)行(xing)星(xing)齒輪(lun)系(xi)(xi)統(tong)各部件的(de)(de)振(zhen)動(dong)(dong)(dong)(dong)，在風(feng)(feng)(feng)力(li)(li)(li)(li)機(ji)(ji)(ji)(ji)行(xing)星(xing)齒輪(lun)設計時(shi)必須考慮(lv)搭(da)架(jia)(jia)的(de)(de)柔性(xing)(xing)(xing)特性(xing)(xing)(xing)對風(feng)(feng)(feng)力(li)(li)(li)(li)機(ji)(ji)(ji)(ji)的(de)(de)影(ying)響。
