感恩關注iHF齒輪學院

上周末，iHF齒輪(lun)學院“在線(xian)問(wen)答”欄目收到關(guan)于齒輪(lun)動態特性的問(wen)題。今天我們來兌現更(geng)詳(xiang)細的解(jie)說了。

齒輪(lun)的動(dong)態特性有齒輪(lun)的固定(ding)性、動(dong)態性、動(dong)態參數等三大特性。 

01.固有特性

齒(chi)輪(lun)的(de)固(gu)(gu)(gu)定性指的(de)是驅動(dong)(dong)(dong)系(xi)統的(de)固(gu)(gu)(gu)有的(de)傳動(dong)(dong)(dong)頻率和模式。齒(chi)輪(lun)的(de)固(gu)(gu)(gu)定特(te)性是齒(chi)輪(lun)系(xi)統的(de)動(dong)(dong)(dong)態特(te)性重要的(de)組(zu)成部分之一。其主要特(te)點對(dui)齒(chi)輪(lun)系(xi)統的(de)固(gu)(gu)(gu)定傳動(dong)(dong)(dong)頻率與(yu)模式通(tong)過參數方(fang)法進(jin)行研究的(de)一種(zhong)方(fang)式。

通過有(you)限元法計算(suan)齒(chi)輪(lun)(lun)和箱體結(jie)構的(de)(de)固有(you)頻率和模式(shi)。運(yun)用對齒(chi)輪(lun)(lun)系統(tong)(tong)的(de)(de)靈敏(min)度(du)、動(dong)態優化設計來研究齒(chi)輪(lun)(lun)系統(tong)(tong)的(de)(de)結(jie)構、幾何、傳動(dong)規律(lv)、模式(shi)等(deng)參數， 并對其進(jin)行相應的(de)(de)改進(jin)，提(ti)高傳動(dong)系統(tong)(tong)的(de)(de)固有(you)特性。 

02.動態響應

齒(chi)輪(lun)(lun)系(xi)統(tong)在動(dong)態(tai)作用(yong)下的(de)(de)(de)動(dong)態(tai)響應(ying)是齒(chi)輪(lun)(lun)系(xi)統(tong)動(dong)力學研究的(de)(de)(de)主要部(bu)分，包(bao)括(kuo)齒(chi)輪(lun)(lun)的(de)(de)(de)在傳動(dong)過(guo)程中的(de)(de)(de)嚙合以及零部(bu)件(jian)的(de)(de)(de)動(dong)態(tai)響應(ying)等。

研究齒(chi)的(de)動(dong)(dong)(dong)態(tai)嚙合力主(zhu)要是了解齒(chi)輪(lun)動(dong)(dong)(dong)態(tai)產生的(de)機理、尺寸、性(xing)質等(deng)。齒(chi)輪(lun)的(de)驅動(dong)(dong)(dong)系(xi)統(tong)(tong)(tong)是一個參(can)數激勵的(de)傳動(dong)(dong)(dong)系(xi)統(tong)(tong)(tong)，與其(qi)它機械振動(dong)(dong)(dong)系(xi)統(tong)(tong)(tong)不(bu)同的(de)是齒(chi)輪(lun)驅動(dong)(dong)(dong)系(xi)統(tong)(tong)(tong)具有動(dong)(dong)(dong)態(tai)穩定性(xing)問題。通過對齒(chi)輪(lun)傳動(dong)(dong)(dong)系(xi)統(tong)(tong)(tong)的(de)動(dong)(dong)(dong)態(tai)穩定性(xing)問題進(jin)行分析，找出其(qi)影響穩定性(xing)的(de)關(guan)鍵原因所在，為齒(chi)輪(lun)傳動(dong)(dong)(dong)系(xi)統(tong)(tong)(tong)的(de)相關(guan)設計(ji)提供參(can)考。 

03.動態系統參數

齒(chi)輪動態系(xi)統(tong)參數主要(yao)是(shi)進(jin)行對齒(chi)輪在傳(chuan)動過程中(zhong)各種(zhong)動態性能的(de)研(yan)究，是(shi)研(yan)究齒(chi)輪系(xi)統(tong)動性能對齒(chi)輪傳(chuan)動的(de)影響。

通過(guo)對(dui)行(xing)星齒輪(lun)(lun)傳動(dong)(dong)系統(tong)(tong)動(dong)(dong)力學靈敏度(du)分(fen)析，定量各種齒輪(lun)(lun)系統(tong)(tong)靈敏度(du)參數以對(dui)齒輪(lun)(lun)在系統(tong)(tong)在傳動(dong)(dong)過(guo)程中的動(dong)(dong)態進(jin)行(xing)優化設計。
