| 摘要:针对某系列发动机机油消耗偏高的问题,基于CAE对活塞二阶运动、活塞环动力学和机油消耗特性进行了分析,找出影响机油消耗的主要原因,并指导活塞、环组的改进设计工作。改进后样件的相关试验验证表明:CAE预测值与试验值较吻合,改进设计在机油消耗方面得到了较满意的效果。 |

| Abstract:Aimed at the high oil consumption of a certain series of engines, the piston two order motion, piston ring dynamics and lube oil consumption characteristics were analyzed based on CAE, and the main reasons to cause high oil consumption were found out, which contributed to the improvement of piston and piston ring series. The sample after improvement was verified through tests, it showed that the CAE data coincided well with the test data, and achieved satisfied effect in lube oil consumption. |
