摘要
根据作者几年来对发动机寿命研究的大量实验数据,运用磨合理论,对位置精度和发动机寿命之间的关系作了较深入的分析,并建立了位置精度对发动机寿命影响的数学模型。
Experimental results on engine life and theory of engine wear-in are apllied in this paper, then an analysis of the relation between position accuracy and engine life is given. In addition. mathematical madel of the effect of position accuracy upon engine life is set up.
