“…In order to prevent the influence of the first ring guide without chromium plated ring on the research results of air tightness, the second and third gas rings were moved up to the first and second ring guides. Oil film thickness measuring system based on the contact resistance principle [12,15,20,30] was assembled in the tester. Two wires were tied to cylinder liner and piston ring respectively.…”

The performance of cylinder liner-piston ring (CLPR) affects the efficiency of marine engine greatly. An experimental study on textured CLPR was conducted to seek insight into the operation reliability of CLPR. Three types of surface texture, groove texture on cylinder liner, dimple texture on piston ring, and co-texture on both sides, were processed. A series of tests were then carried out on an engine tester. Three characterization parameters, contact resistance, worn surface topography on cylinder liner, and cylinder pressure were used to describe the CLPR tribological properties and air tightness. The results showed that the three textures all improved tribological properties. Compared to the non-textured surface, the contact resistance of the three textures increased 30.7%, 71.7% and 98.4% on average. The wear resistance of dimple texture was weaker than that of groove texture. Air tightness was closely related to oil film pressure. At dead centre, the cylinder pressure of the three textures respectively was optimized by 4.6 kPa, 7.8 kPa and 12.3 kPa averagely. The co-texture was shown to combine the advantages of groove texture with the advantages of dimple texture, which provided the surface with improved oil film distribution and more efficient debris trapping, resulting in the optimum tribological properties and air tightness among the three textures.

“…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.

“…Previous researchers have reported the general methods for reducing material abrasion, including enhancing the wear resistance of the material surface using wear-resistant materials or coating the surface of the material with one having a better wear resistance. However, this may increase the cost [3][4][5][6][7][8].…”

In order to improve the forming quality of automobile body cover parts, the trundle attrition between the roller and panel in a roll-wrap robot has been investigated to minimize the frictional losses. This paper presents a design scheme of bionic roller structure based on the surface texture of pearl shell. The microstructure of pearl shell surface is analyzed and the mapping model of pearl shell surface structure is established. Meanwhile, the best texture type is determined by simulation analysis and theoretical formula. Based on the optimal texture type, the optimized roller structure is simulated and analyzed by utilizing the golden section method to determine the best depth-to-width ratio. The roller model is made by 3D laser marking mechanism. The validty of the theory and design method is verified by the correspoding experiments. By comparing the simulation and experimental analysis data, it can be seen that the vertical stripe bionic roller achieves the optimal performance when the depth-to-width ratio is 0.382. Compared with the ordinary roller, the maximum principal stress at the node is reduced by 2038.5 N, the frictional loss energy during movement is reduced by 8.43 × 108J, the wear mass is reduced by 285.63%, the wear depth is reduced by 47.4%.
