中文摘要：
建立了含固体颗粒的弹流润滑模型,推导了考虑颗粒效应的Reynolds方程,考虑了时变效应、载荷和转速,对直齿轮跑合进行了弹流润滑分析。结果表明：颗粒所在区域2的油膜压力显著增大,考虑颗粒后的膜厚减小。颗粒尺寸增大,油膜压力增大,膜厚减小。载荷增大,颗粒所在区域2的油膜压力增大,膜厚减小。转速越小,固体颗粒效应越明显,油膜压力变化显著,膜厚变小。考虑固体颗粒后的最小膜厚和最大压力均变小,中心油膜压力有所增大,中心膜厚减小。
英文摘要：
The elastohydrodynamic lubrication model considering solid particles is set up. The Reynolds equation is deduced taking effect of solid particles into account. The elastohydrodynamic lubrication analysis of spur gear running-in is completed considering time-variant effect, load and rotate speed. Results show that oil film pressure in region 2 where particle is located increases dramatically but oil film thickness in region 2 decreases thinking about effects of solid particles. When particle size becomes greater oil film pressure increases obviously, oil film thickness diminishes. The oil film pressure in region 2 increases along with greater load, but oil film thickness in region 2 decreases along with greater load. When rotate speed becomes smaller effects of solid particles are evident, variation of oil film pressure is remarkable, oil film thickness becomes thinner. The minimum film thickness and maximum film pressure both diminish considering effects of solid particles. The centre film pressure increases and the centre film thickness decreases taking effects of solid particles into consideration.
