近五年来看到了在活塞环动力学润滑这一问题上有了很大进展。但是,由于这些分析必然是很复杂的,致使它的全部重要性未被人们广泛地重视。本文作者企图不用详细的数学方法来描述活塞环及气缸套的动力学及润滑某些方面的推理和结论。期望用本文所述方法使活塞环分析的广度及用途能较好地被人们所接受,以便更好地利用它们。文章讨论了活塞环的动力相似性,并把所有活塞环密封面上自成的磨损外形的测量结果看作是造成拉缸的特征指标。
In the last five years, great progress has been made on the issue of dynamic lubrication of piston rings. However, due to the inevitable complexity of these analyzes, the full importance of the analysis has not been given much attention. The author attempts not to use detailed mathematical methods to describe the dynamics and lubrication of piston ring and cylinder liner in some aspects of reasoning and conclusions. It is expected that the breadth and purpose of piston ring analysis, as described herein, will be better accepted for better utilization. The article discusses the dynamic similarity of piston rings and considers the measurement of the self-forming wear profile of all piston ring sealing surfaces as a characteristic indicator of the cylinder.
