“…However, the texture parameters do not exert a notable impact on the friction coefficient. Chen et al (2022) comparatively analyzed the effects of different circular groove texture parameter configurations on improving the loadbearing capacity of thrust bearings. Research suggests that the optimal load-bearing performance was achieved when both the texture diameter and depth were set to 5 mm.…”

Purpose This paper aims to study the influence of cylindrical texture parameters on the lubrication performance of static and dynamic pressure thrust bearings (hereinafter referred to as thrust bearings) and to optimize their lubrication performance using multiobjective optimization. Design/methodology/approach The influence of texture parameters on the lubrication performance of thrust bearings was studied based on the modified Reynolds equation. The objective functions are predicted through the BP neural network, and the texture parameters were optimized using the improved multiobjective ant lion algorithm (MOALA). Findings Compared with smooth surface, the introduction of texture can improve the lubrication properties. Under the optimization of the improved algorithm, when the texture diameter, depth, spacing and number are approximately 0.2 mm, 0.5 mm, 5 mm and 34, respectively, the loading capacity is increased by around 27.7% and the temperature is reduced by around 1.55°C. Originality/value This paper studies the effect of texture parameters on the lubrication properties of thrust bearings based on the modified Reynolds equation and performs multiobjective optimization through an improved MOALA.

The internal combustion engine will be required as a bridge-technology in the upcoming decades to achieve a significant reduction in local emissions in the mobility, and logistics sector. Alternative fuel technologies will present new mechanical engineering challenges, including increasing efficiency and reducing mechanical losses. Textured surfaces with appropriate manufacturing parameters can enhance lubrication, and reduce friction in sliding and rolling contacts, e.g., journal bearings, or the piston ring -cylinder subsystem. This paper gives an overview of 80 scientific works related to laser surface technologies, with an emphasis on surface texturing for friction reduction from the viewpoint of engine development. The most common texture types, further directions, and general challenges are highlighted in the summary.

One of the most needed requirements for developing technology in our today's world is to have a long life of sealant structures used in oil and gas and other industries. In turn, that makes it important to conduct more in-depth research on these structures and improve the achieved results [1]. There are several constructions included in the sealant structures and one of them is valves [2]. Nowadays, valves are being majorly used in industry. They are calculated to various pressures and being applied in different processes. The frequently malfunctioning valves are the ones being used at high pressures among the assemblies [2, 3].
