Tribological Performance of Fibre Reinforced Poly-Ether-Ether-Ketone
Indian Journal of Engineering and Materials Sciences, 1998Co-Authors: A. P. Harsha, Braham Prakash, U. S. TewariAbstract:The Tribological Performance of carbon and glass fibre reinforced poly-ether-ether-ketone (PEEK) for parallel (P) and normal orientation (N) has been conducted on pin-on-disc machine under dry sliding conditions. The influence of variables such as sliding distance, load, velocity, abrasive grit size has been investigated. It was observed that fibre orientation has a significant influence on Tribological Performance of the polymer composites. An increased friction and wear was observed for parallel fibre orientation than normal fibre orientation. The dependence of the wear rate on the fibre orientation is difficult to model in a quantitative manner.

Evaluation on the Tribological Performance of ring/liner system under cylinder deactivation with consideration of cylinder liner deformation and oil supply.
PLOS ONE, 2018Co-Authors: Yanjun Lu, Yafeng Du, Jiahui Wang, Yongfang Zhang, Norbert MüllerAbstract:In gasoline engines, CDA (cylinder deactivation) affects greatly the Tribological Performance of ring/liner system while reducing the emissions and improving the fuel economy. The analyses on the Tribological Performance of ring/liner system under the CDA mainly focus on the ideal circular cylinder liner and fixed fully flooded lubrication condition. In this study, a numerical investigation on the Tribological Performance of a compression ring-cylinder liner system is presented under the CDA with consideration of the cylinder liner deformation and the transition between the fully flooded and starved lubrication conditions. A mixed lubrication model coupled with oil transport model and JFO (Jacobson-Floberg-Olsson) conservative cavitation algorithm is proposed to evaluate the frictional properties. Based on the model, the Tribological Performance is investigated under the standard operation condition and the CDA. Meanwhile, the influence of cylinder liner deformation and oil supply on the Tribological Performance is also evaluated. Results show that the Tribological Performance of the compression ring-cylinder liner system is greatly changed when the CDA is adopted. In particular, under the CDA, the overall power loss and FMEP (friction mean effective pressure) value are increased about 27.29% and 53.51%. The study also demonstrates the necessity to consider the cylinder liner deformation and oil supply in the simulation of compression ring-cylinder liner system under the CDA.

Numerical Study on the Tribological Performance of Ring/Liner System With Consideration of Oil Transport
Journal of Tribology-transactions of The Asme, 2018Co-Authors: Yanjun Lu, Jianxiong Kang, Sha Li, Yongfang Zhang, Norbert MüllerAbstract:The Tribological Performance of a compression ring-cylinder liner system (CRCL) is numerically studied. A thermal-mixed lubrication model is developed for the lubrication analysis of the CRCL with consideration of the cylinder liner deformation. An oil transport model coupled with a mass conservation cavitation algorithm is employed to predict the oil consumption and the transition between the fully flooded lubrication condition and starved lubrication condition. On this basis, the effects of the oil supply and cylinder liner deformation on the frictional characteristics are investigated under cold and warm engine conditions. The results show that the cylinder liner deformation and oil supply have great influence on the Tribological Performance of the CRCL. Better Tribological Performance and lower oil consumption can be obtained by reasonably controlling the oil supply.
