内燃机缸套磨损预测研究

CYLINDER BORE WEAR PREDICTION OF INTERNAL COMBUSTION ENGINE

磨损预测是个极为复杂的问题。完全依赖实验方法进行预测不仅耗资而且费时,因此需要理论计算与实验相结合,来解决机械设计中零部件磨损的预测问题。根据上述思想,作者研究了内燃机的主要摩擦付中缸套的磨损预测,并在实验的基础上修正了原有的计算公式,编制了计算软件。作者将试验和实用内燃机缸套测量的磨损数据与计算结果进行了比较。

Wear prediction is a complex problem.If depending entirely on.It will take much time and wuch money.Hence it is advisable to combine theoretical calculation with experiment for wear prediction of parts and components in mechanical design.This paper analyzed the calculation method of four main wear form of cylinder bore.(i.e.adhesive wear,abrasive wear,corrosive wear and fatigue wear) Based on experimental result,the original calculation method modified.Authors measured the cylinder wall wear of diesels and compaired the calculation with that of measurement.
