Improving running-in quality is an important project of Green Tribology. In actual environment, the running-in quality of mechanical equipment is greatly affected by system parameters. In view of this, running-in experiments were performed at different rotating speeds on a pin-on-disc tribometer. Chaos theory was used to investigate the effect of rotating speeds on the running-in quality. The experimental results showed that the running-in quality could be better evaluated by using the chaotic characteristic parameter “Convergence (CON)”. The greater the CON, the better the running-in quality. With an increase of the rotating speed, CON first gradually increased and then decreased to a certain level, whilst the running-in quality first gradually became better and then became worse. A moderate rotating speed is advantageous to obtain the optimum running-in quality. This contributes to the service life extension and the efficiency improvement, so as to reduce energy consumption.

混沌理论研究不同转速下的磨合质量

提高磨合质量是绿色摩擦学的一个重要项目。在实际环境中，机械设备的磨合质量受系统参数的影响很大。鉴于此，在销盘式摩擦计上以不同的转速进行了磨合实验。混沌理论用于研究转速对磨合质量的影响。实验结果表明，使用混沌特征参数“Convergence (CON)”。越大CON，磨合质量越好。随着转速的增加，CON磨合质量先逐渐上升后下降到一定水平，而磨合质量则先逐渐好后变差。适中的转速有利于获得最佳的磨合质量。这有助于延长使用寿命和提高效率，从而降低能耗。
