| 摘 要： | 为了研究高原环境对柴油机寿命的影响,以某型柴油机为对象,通过模拟高原柴油机实际工作过程,结合活塞环受力分析和缸套传热计算得到边界条件,基于雷诺方程和改进的Holm-Achard黏着磨损公式建立气缸套-活塞环润滑磨损数值计算模型;经验证气缸套径向最大磨损深度的计算值与实测值误差不超过5%。计算表明,油膜厚度随外界大气压力降低而逐渐变薄;在海拔5000 m左右时气缸平均磨损值达到最大。

| Abstract: | In order to research the operating conditions effects on diesel life,a certain diesel through simulating the actually conditions of the altiplano diesel.The cylinder liner-piston ring boundary condition was established with dynamic and heat balance analysis.The lubrication and wear calculation mode was established based on mean Reynolds equation and Holm-Achard sticking wear mechanics.The results show that,the error of the calculated value of maximum radial wear depth of cylinder liner is lower than 5% comp... |
