“…Contact interfaces between immobile bodies, such as bolted joints and roller bearings, are essential in machine tools for the fixed connection and force transmission of structures (Du et al, 2015; Ibrahim and Pettit, 2005; Liu and Shao, 2017, 2018). Normal contact stiffness is a basic parameter for characterizing both the static and dynamic behaviors of the rough interface, including pressure distribution, natural frequency, and so on (Putignano et al, 2011; Xiao and Sun, 2019).…”

In this work, the normal contact stiffness of lubricated rough interface is evaluated theoretically by describing the lubricated rough interface as an equivalent thin layer. Layer parameters, including equivalent thickness and effective Young’s modulus, are used to characterize the normal contact stiffness by incorporating the contributions of asperity contact and lubricant contact simultaneously. On the basis of layer parameters, the normal contact stiffness of lubricated rough interface is obtained as a function of interfacial separation, surface topography, and properties of contacting solids and lubricants. Effects of surface topographies and lubricant types on the normal contact stiffness are investigated at varying interfacial separations and contact area fractions. The proportion of solid stiffness and lubricant stiffness from the total normal stiffness is also discussed. Numerical solutions reveal that the normal contact stiffness depends sensitively on the lubricant property at initial contact, whereas the influences of surface topographies become obvious with the decrement of interfacial separation or increment of contact area fraction. Comparisons between the predicted values of normal contact stiffness and experimental data for both dry interface and lubricated interface are presented to validate the rationality of the developed model.

Friction squeal is an unstable friction-induced vibration with high frequency and high intensity, which is troublesome for both people and environment. Surface topography is an important influencing factors of friction squeal. In this paper, based on introduction of surface topography, a review on the influence of surface topography on friction squeal is conducted from the aspect of experimental analysis, theoretical research and simulation analysis. For the convenience of scholars’ understanding and carrying out relevant research, the influence of surface topography on friction and contact parameters, and the influence of friction and contact parameters on friction squeal are reviewed. Moreover, the generation methods of rough surface are introduced to facilitate the research. Finally, on the basis of a discussion on difficulties and shortcomings of the former research, recommendations are proposed for future research.

“…Dwyer-Joyce et al [25] used a CAN model in a feasibility study for the measurements of wheel-rail contact pressure distribution with a one-dimensional ultrasonic transducer array and line scan. Similarly, Du et al [26] utilized the CAN model to transform the proportion of reflected ultrasonic waves into the contact stiffness measurements at the interface. Most analytical or numerical models in the above studies are univariate such as the pressure-dependent or frequency-dependent stiffness functions under one-dimensional contact tests.…”

In an attempt to analyze the feasibility of a rail monitoring scheme with a wheel-mounted acoustic emission measurement method, a two-dimensional analytical spring model was proposed to interpret the interactions between acoustic waves and stationary wheel-rail contact interfaces. The spring model represents the coupling strength of the interfaces with their stiffness. It accommodates the environmental information of contact stiffness and the acoustic source information, such as the feature frequency and the incident angle in the analysis of interface transmissibility. The fractal dimension of the interface is introduced into the spring model to interpret the effect of the axle load on the interface stiffness and the variation in transmissibility. Discrete Rayleigh integration is further combined to obtain the directivity of the interface and estimate the acoustic field intensity in the entire wheel. A wheel-rail contact rig was designed to simulate the actual contact conditions in a railway. Experimental data acquired from this test rig were utilized to validate the model, with regard to the interfacial stiffness in normal incidence and amplitudes of the transmitted waves in oblique incidence. After verifying the reliability of the model, the acoustic field intensity in the wheel was visualized under the assumed environmental conditions. Finally, a discussion is presented to determine a proper angular separation for the wheel-mounted sensor system, and substantiate the feasibility of the system.
