【摘要】：本文基于流體潤(rùn)滑理論建立分析模型,對(duì)高速低黏度潤(rùn)滑劑滑動(dòng)軸承潤(rùn)滑性能進(jìn)行了研究,主要分析邊界條件、潤(rùn)滑劑湍流慣性和供油條件等對(duì)高速低黏度潤(rùn)滑劑滑動(dòng)軸承潤(rùn)滑性能的影響。 首先,不考慮潤(rùn)滑劑湍流慣性及供油條件的影響,使用改進(jìn)的Elrod質(zhì)量守恒算法(包含質(zhì)量守恒邊界條件)求解Reynolds方程,將結(jié)果與雷諾邊界條件結(jié)果進(jìn)行對(duì)比,分析不同邊界條件下軸承潤(rùn)滑性能的區(qū)別。然后,在質(zhì)量守恒算法的基礎(chǔ)上,考慮軸承中潤(rùn)滑劑湍流流動(dòng)與慣性的影響,使用平均速度場(chǎng)模式理論建立分析模型,計(jì)算軸承潤(rùn)滑性能參數(shù),并分析湍流及慣性對(duì)各性能參數(shù)的影響。最后,綜合質(zhì)量守恒算法與湍流慣性模型并考慮實(shí)際供油條件,計(jì)算分析不同供油壓力及油槽位置下的軸承潤(rùn)滑性能。 使用質(zhì)量守恒算法可以使滑動(dòng)軸承潤(rùn)滑分析更加接近實(shí)際情況,湍流慣性的影響是高速低黏度潤(rùn)滑劑滑動(dòng)軸承潤(rùn)滑分析必須考慮的內(nèi)容,對(duì)不同供油壓力和油槽位置時(shí)軸承潤(rùn)滑性能的分析有助于尋找合理的軸承設(shè)計(jì)方案。本文分析是針對(duì)某發(fā)動(dòng)機(jī)燃油泵滑動(dòng)軸承進(jìn)行的,使用的軸承結(jié)構(gòu)參數(shù)(半徑、寬度和間隙等)為固定值,若改變這些結(jié)構(gòu)參數(shù),本文的方法也適用于其它機(jī)械裝置滑動(dòng)軸承潤(rùn)滑分析。
[Abstract]:Based on the theory of fluid lubrication, the lubrication performance of high speed and low viscosity lubricant sliding bearings is studied in this paper, and the boundary conditions are mainly analyzed. The influence of lubricant turbulence inertia and oil supply condition on lubricating performance of high speed low viscosity lubricant sliding bearing. Firstly, the modified Elrod mass conservation algorithm (including mass conservation boundary condition) is used to solve the Reynolds equation without considering the influence of lubricant turbulent inertia and oil supply condition. The results are compared with the results of Reynolds boundary condition, and the difference of lubricating performance of bearing under different boundary conditions is analyzed. Then, based on the mass conservation algorithm, the effects of lubricant turbulent flow and inertia in bearing are considered. The analysis model is established by using the model theory of average velocity field, the lubrication performance parameters of bearing are calculated, and the effects of turbulence and inertia on the performance parameters are analyzed. Combined with mass conservation algorithm and turbulent inertial model and considering the actual oil supply conditions, the lubrication performance of bearing under different oil supply pressure and tank position is calculated and analyzed. Using the mass conservation algorithm can make the lubrication analysis of sliding bearing closer to the actual situation. The influence of turbulent inertia is the content that must be considered in the lubrication analysis of high speed low viscosity lubricant sliding bearing. The analysis of lubricating performance of bearing under different oil supply pressure and tank position is helpful to find a reasonable bearing design scheme. This analysis is aimed at the sliding bearing of a certain engine fuel pump. The structural parameters (radius, width, clearance, etc.) of the bearings used are fixed values. If these structural parameters are changed, the method in this paper is also suitable for the lubrication analysis of other mechanical sliding bearings.
