RISInvestigation of the Optimum Surface Roughness of AISI 5120 Steel by Using a Running-in Attractor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To investigate the influence of surface roughnesses on the dynamic characteristics of AISI 5120 steel in sliding friction process, a suite of running-in experiments are performed on a pin-on-disk tribometer. The running-in ...
Multifractal Detrended Fluctuation Analysis on Friction Coefficient During the Friction Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic evolutionary law and tribological behavior of tribopair AISI 52100-AISI 1045 were studied via the multifractal method. Friction experiment was performed on a ring-on-disk tribometer under lubrication, and the ...
Dynamic States Recognition of Friction Noise in the Wear Process Based on Moving Cut Data-Approximate Entropy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wear experiments are performed to explore dynamic states changes of friction noise signals. A new characteristic parameter, moving cut data-approximate entropy (MC-ApEn), is adopted to quantitatively recognize dynamic ...
Multivariate Graph-Based Analysis on Coefficient of Friction Signal During the Friction Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To describe the dynamic evolutionary law and tribological behavior of the tribopair AISI 52100-AISI 1045, rotational experiments were conducted by sliding a disk against a static pin. The multidimensional phase spaces were ...
A Recursive Characteristics Analysis-Based Stationarity Evaluation Model for Friction-Induced Attractors in the Sliding Friction Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the coefficient of friction (COF) signals throughout the running-in process were examined by sliding a ring against a static disc. By reconstructing the scalar time-series into multi-dimensional phase spaces, ...
