Chaotic Characteristics Study on Cylinder Liner-Piston Ring's Friction Signal
[摘要] Cylinder linear-piston ring is the most important frication pairs in the internal combustion engine and the friction signal can reflect the characteristics of the whole tribological system. The wear test was carried out using UMT-3 tester and the friction signal was denoised via wavelet technology for the determination of chaotic characteristics by principal component, the largest Lyapunov exponent and the Kolmogorov entropy. The results indicated that chaos theory is applicable to the research of cylinder linear-piston ring wear system due to its chaotic characteristics, which is of great significance to the tribological design and the identification of the state of wear process.
