“…Ville and Né lias (1999) conducted the experiments using several typical particles to study their influence on rolling contact. The threedimensional morphology of the debris particles was extracted in an effort to determine the operating conditions of the equipment (Guo et al, 2014;Rao et al, 2019;Yuan et al, 2007). Vibration and acoustic emission are common tools for monitoring contaminated bearings.…”

Rolling bearings operating in harsh environments are extremely exposed to the risk of exogenous dust or wear debris particles, so there is a strong need to investigate the effects of particulate contamination on bearing operation and to identify problems early. The lubricated oil containing silica particles of various sizes and concentrations are prepared and introduced into thrust ball bearings to replicate the severe operating conditions. Vibration and acoustic emission (AE) signals were measured by accelerometer and AE sensor in a thrust ball bearing test rig. The experimental bearing raceway was observed by scanning electron microscope (SEM) and confocal laser scanning microscopy, and the evolution of the surface topography was analyzed to probe the wear mechanism. The results show that the most severe wear areas occur at the bottom of the bearing raceway, and its degree of wear is significantly influenced by the size and concentration of the silica particles. As the experimental time increases, the raceway surface undergoes an accelerated wear process originating from slight dimples, which leads to bearing failure. Furthermore, the introduction of particles into the lubricant increases surface root mean square (RMS) roughness, vibration and acoustic emission for different experimental durations. The vibration and AE signals are affected by a combination of solid particles and surface wear. The measured monitoring results can provide valuable information about the damage morphologies and subsequently about the state of the bearing during operation.

“…The excessive wear of some core parts of machineries, especially for large-scale mechanical equipment, may lead to a poor mechanical performance, which in turn causes enormous economic losses. Therefore, for online monitoring of the wear condition of machineries in order to prevent serious malfunctions, the wear particle detector has demonstrated its value [1,2,3]. To date, wear particle detectors with different physical principles, including optics, ultrasonics, electronics, and imaging, have been proposed, and the characteristics of the various kinds of sensors are listed in Reference [4].…”

The electromagnetic wear particle detector has been widely studied due to its prospective applications in various fields. In order to meet the requirements of the high-precision wear particle detector, a comprehensive method of improving the sensitivity and detectability of the sensor is proposed. Based on the nature of the sensor, parallel resonant exciting coils are used to increase the impedance change of the exciting circuit caused by particles, and the serial resonant topology structure and an amorphous core are applied to the inductive coil, which improves the magnetic flux change of the inductive coil and enlarges the induced electromotive force of the sensor. Moreover, the influences of the resonance frequency on the sensitivity and effective particle detection range of the sensor are studied, which forms the basis for optimizing the frequency of the magnetic field within the sensor. For further improving the detectability of micro-particles and the real-time monitoring ability of the sensor, a simple and quick extraction method for the particle signal, based on a modified lock-in amplifier and empirical mode decomposition and reverse reconstruction (EMD-RRC), is proposed, which can effectively extract the particle signal from the raw signal with low signal-to-noise ratio (SNR). The simulation and experimental results show that the proposed methods improve the sensitivity of the sensor by more than six times.

“…Classification of wear particles is an important task in wear particle analysis, and high identification rates are conducive to reliably monitor the machine condition and objectively assess the wear mechanism [25]. For instance, Stachowiak et al developed an automated classification system based on surface textures and shape features of the wear particles, and the results showed that the texture-based classification system was efficient and accurate [26].…”

Wear is a crucial factor that limits the operational lifespan of the cylinder liner-piston ring (CLPR) in marine diesel engines. Efforts had been made to reduce wear by grooving textures on the cylinders. Besides, the influence of surface textures on mechanical wear can be evaluated by wear particle analysis. This study aims to characterize features of wear particles generated from different surface textured cylinder liners and investigate the relationship between the texture and wear particle features. Wear particles generated from liners of different groove angles (30°, 45°, 60°) and different widths (1 mm, 2 mm, 3 mm, 4 mm) were collected from friction tests, and the characteristics were obtained using a 3D laser microscope. Then, comparative studies on the 2D characteristics and 3D surface topographies of wear particles were performed. Results revealed that the characterization parameters of wear particles can be used to identify the different types of surface texture and reflect the lubrication performance of the friction pairs. Specifically, wear particles generated from the 2 mm width with 30°a ngular grooved texture were different from the others, and it effectively improved lubrication in the CLPR friction pair. These results can be used as a reference for the application of surface textures on CLPR pairs for improved lubrication.
