中文摘要：
利用考虑热效应、磁场和时变的Reynolds方程,对带有余弦粗糙度的轴和轴承表面进行水基磁流体弹流润滑分析,并探讨了在第15瞬时时,磁感应强度和磁粉体积分数对水基磁流体润滑膜压力、膜厚和温度的影响。结果表明：水基磁流体润滑膜的压力和温度随着磁感应强度的增大而减小,膜厚随着磁感应强度的增大而增大;润滑膜的压力和温度随着磁粉体积分数的增大而减小,膜厚随着磁粉体积分数的增大而增大。
英文摘要：
The Reynolds equation considering the heat effect,magnetic field and transient is used,and the water-based ferrofluid EHL analysis is carried out for the shaft and bearing surface with cosine roughness. The influences of magnetic induction intensity and magnetic particle volume fraction on the pressure,thickness and temperature of water- based ferrofluid lubricating film at the 15th instant are discussed. The results show that the pressure and temperature of water- based ferrofluid lubricating film decreases with the increase of magnetic induction intensity,the film thickness increases with the increase of magnetic induction intensity; the pressure and temperature of lubricating film decreases with the increase of magnetic particle volume fraction,the film thickness increases with the increase of magnetic particle volume fraction.
