【摘要】：對(duì)球盤(pán)點(diǎn)接觸區(qū)域潤(rùn)滑劑的動(dòng)態(tài)流動(dòng)特性進(jìn)行研究,利用高速攝影技術(shù)實(shí)時(shí)捕捉點(diǎn)接觸區(qū)域潤(rùn)滑劑的流動(dòng)情況,結(jié)合CFD軟件FLUENT的計(jì)算結(jié)果,對(duì)不同卷吸速度下點(diǎn)接觸區(qū)域潤(rùn)滑劑的速度場(chǎng)進(jìn)行分析。結(jié)果表明:潤(rùn)滑劑在點(diǎn)接觸區(qū)域的流動(dòng)基本處于層流狀態(tài),在流經(jīng)接觸區(qū)域時(shí)出現(xiàn)了先匯聚后分離的現(xiàn)象,且這種現(xiàn)象隨卷吸速度的增加有所增強(qiáng);潤(rùn)滑劑在接觸區(qū)域的速度大小與其所處位置有關(guān),在入口附近速度有急劇增加的現(xiàn)象,這種現(xiàn)象隨卷吸速度的增加逐漸向兩側(cè)偏移并減弱。
[Abstract]:The dynamic flow characteristics of the contact area of the ball on the inventory of lubricant flow, using high-speed photography to capture real-time contact area of lubricant, combined with the calculation results of CFD software FLUENT, the different entrainment velocity under point contact region lubricant velocity field analysis. The results show that the basic lubricant in the laminar state in point contact area the flow passes through the contact area when the first sink after separation of the phenomenon, and this phenomenon with the increase of the entrainment velocity is increased; the speed of lubricant in the contact region size and location, there is a sharp increase in the phenomenon near the entrance speed increase, this phenomenon with the entrainment velocity gradually to both sides the offset and weakened.
