感(gan)恩關(guan)注iHF齒輪學院

上(shang)周末，iHF齒輪(lun)學院(yuan)“在線(xian)問答”欄目(mu)收到關于(yu)齒輪(lun)動態特性的問題。今天我(wo)們來(lai)兌現(xian)更(geng)詳(xiang)細的解說了。

齒輪的動(dong)態(tai)(tai)特性(xing)(xing)有齒輪的固定(ding)性(xing)(xing)、動(dong)態(tai)(tai)性(xing)(xing)、動(dong)態(tai)(tai)參數等三大特性(xing)(xing)。 

01.固有特性

齒(chi)輪的(de)固(gu)(gu)定性(xing)指的(de)是(shi)驅動(dong)系統(tong)的(de)固(gu)(gu)有的(de)傳(chuan)動(dong)頻(pin)率(lv)和模式(shi)。齒(chi)輪的(de)固(gu)(gu)定特(te)(te)性(xing)是(shi)齒(chi)輪系統(tong)的(de)動(dong)態(tai)特(te)(te)性(xing)重要(yao)的(de)組成部分之一。其主要(yao)特(te)(te)點對齒(chi)輪系統(tong)的(de)固(gu)(gu)定傳(chuan)動(dong)頻(pin)率(lv)與模式(shi)通過參數(shu)方法進(jin)行研究的(de)一種方式(shi)。

通過有限元法計算齒(chi)(chi)輪和(he)箱體結構的(de)固有頻率和(he)模式。運(yun)用(yong)對(dui)齒(chi)(chi)輪系(xi)統的(de)靈敏(min)度、動(dong)態優化設計來研究齒(chi)(chi)輪系(xi)統的(de)結構、幾(ji)何、傳動(dong)規律、模式等(deng)參(can)數， 并(bing)對(dui)其進行相應的(de)改進，提高傳動(dong)系(xi)統的(de)固有特(te)性。 

02.動(dong)態(tai)響(xiang)應

齒(chi)輪(lun)(lun)系統在(zai)動(dong)態(tai)(tai)作用下的(de)動(dong)態(tai)(tai)響應是齒(chi)輪(lun)(lun)系統動(dong)力學研究的(de)主要部分，包括齒(chi)輪(lun)(lun)的(de)在(zai)傳動(dong)過程中(zhong)的(de)嚙合以(yi)及零部件的(de)動(dong)態(tai)(tai)響應等。

研究齒(chi)(chi)(chi)的動(dong)(dong)(dong)(dong)態(tai)嚙合(he)力主要(yao)是了解齒(chi)(chi)(chi)輪(lun)(lun)(lun)動(dong)(dong)(dong)(dong)態(tai)產(chan)生的機理(li)、尺寸、性(xing)(xing)(xing)質等(deng)。齒(chi)(chi)(chi)輪(lun)(lun)(lun)的驅動(dong)(dong)(dong)(dong)系(xi)統(tong)是一個參數激勵的傳(chuan)動(dong)(dong)(dong)(dong)系(xi)統(tong)，與其它機械振動(dong)(dong)(dong)(dong)系(xi)統(tong)不同的是齒(chi)(chi)(chi)輪(lun)(lun)(lun)驅動(dong)(dong)(dong)(dong)系(xi)統(tong)具有動(dong)(dong)(dong)(dong)態(tai)穩(wen)定(ding)性(xing)(xing)(xing)問題。通過(guo)對齒(chi)(chi)(chi)輪(lun)(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)系(xi)統(tong)的動(dong)(dong)(dong)(dong)態(tai)穩(wen)定(ding)性(xing)(xing)(xing)問題進行分析，找出(chu)其影響穩(wen)定(ding)性(xing)(xing)(xing)的關鍵原因(yin)所在，為齒(chi)(chi)(chi)輪(lun)(lun)(lun)傳(chuan)動(dong)(dong)(dong)(dong)系(xi)統(tong)的相關設計提供參考。 

03.動(dong)態系統(tong)參(can)數

齒(chi)(chi)輪動(dong)(dong)態系統(tong)參數主要是進行對齒(chi)(chi)輪在傳(chuan)動(dong)(dong)過程中各(ge)種(zhong)動(dong)(dong)態性能的(de)研(yan)究(jiu)，是研(yan)究(jiu)齒(chi)(chi)輪系統(tong)動(dong)(dong)性能對齒(chi)(chi)輪傳(chuan)動(dong)(dong)的(de)影(ying)響。

通過(guo)對行星齒輪傳(chuan)動系(xi)(xi)統(tong)動力學靈(ling)敏度分析，定(ding)量各(ge)種齒輪系(xi)(xi)統(tong)靈(ling)敏度參(can)數以對齒輪在系(xi)(xi)統(tong)在傳(chuan)動過(guo)程中的動態進(jin)行優化設計。
