“…According to the Principle of Central Composite design (Huang et al , 2021), this experiment adopted the quadratic rotational orthogonal combination test scheme. Taking width, depth and spacing as the test factors and taking average friction coefficient and average wear mark width as the response indexes, the friction test was carried out to study the primary and secondary effects of each factor as well as the interactions between factors.…”

“…Gruetzmacher et al (2019) elucidated numerical approaches to predict the behavior of multi-scale surface texturing under lubricated conditions and summarized the existing knowledge and hypotheses about the underlying driven mechanisms responsible for the improved tribological performance of multi-scale textures. Huang et al (2021) designed a bionic micro-texture combined with solid lubrication SnAgCu to improve the tribological performance of AISI 4140 steel, and the optimized bionic texture parameters were obtained by the response surface method (RSM). Saeidi et al (2016) investigated the effect of laser surface texturing on the friction behavior and the lifetime of grey cast iron reciprocating under starved lubrication conditions; the results indicated that with the following texture parameters: depth of 50 μm, diameter of 100 μm, length of 500 μm, area fraction of 5% and a sliding direction perpendicular to the micro-textures, the friction coefficient reached its minimum value.…”

Purpose Gears are prone to instantaneous failure when operating under extreme conditions, affecting the machinery’s service life. With numerous types of gear meshing and complex operating conditions, this study focuses on the gear–rack mechanism. This study aims to analyze the effects and optimization of biomimetic texture parameters on the line contact tribological behavior of gear–rack mechanisms under starvation lubrication conditions. Design/methodology/approach Inspired by the microstructure of shark skin surface, a diamond-shaped biomimetic texture was designed to improve the tribological performance of gear–rack mechanism under starved lubrication conditions. The line contact meshing process of gear–rack mechanisms under lubrication-deficient conditions was simulated by using a block-on-ring test. Using the response surface method, this paper analyzed the effects of bionic texture parameters (width, depth and spacing) on the tribological performance (friction coefficient and wear amount) of tested samples under line contact and starved lubrication conditions. Findings The experimental results show an optimal proportional relationship between the texture parameters, which made the tribological performance of the tested samples the best. The texture parameters were optimized by using the main objective function method, and the preferred combination of parameters was a width of 69 µm, depth of 24 µm and spacing of 1,162 µm. Originality/value The research results have practical guiding significance for designing line contact motion pairs surface texture and provide a theoretical basis for optimizing line contact motion pairs tribological performance under extreme working conditions.

Magnetic fluid shock absorbers (MFSAs) have been successfully utilized to eliminate microvibrations of flexible spacecraft structures. The method of enhancing the damping efficiency of MFSAs has always been a critical issue. To address this, we drew inspiration from the tree frog’s toe pads, which exhibit strong friction due to their unique surface structure. Using 3D printing, we integrated bionic textures copied from tree frog’s toe pad surfaces onto MFSAs, which is the first time to combine bionic design and MFSAs. Additionally, this is also the first time that surface textures have been applied to MFSAs. However, we also had to consider practical engineering applications and manufacturing convenience, so we modified the shape of bionic textures. To do so, we used an edge extraction algorithm for image processing and obtained recognition results. After thorough consideration, we chose hexagon as the shape of surface textures instead of bionic textures. For theoretical analysis, a magnetic field–flow field coupling dynamic model for MFSAs was built for the first time to simulate the magnetic fluid (MF) flow in one oscillation cycle. Using this model, the flow rate contours of the MF were obtained. It was observed that textures cause vortexes to form in the MF layer, which produced an additional velocity field. This increased the shear rate, ultimately leading to an increase in flow resistance. Finally, we conducted vibration reduction experiments and estimated damping characteristics of the proposed MFSAs to prove the effectiveness of both bionic texture and hexagon surface textures. Fortunately, we concluded that hexagon surface textures not only improve the damping efficiency of MFSAs but also require less MF mass.

Magnetic fluid shock absorbers (MFSAs) have been successfully applied in eliminating the micro-vibration of the spacecraft’s flexible structures. The method of enhancing the damping of MFSAs has always been the key issue. The tree frog’s toe pads exhibit the strong adhesion, which inspired us to learn from their surface structure. We got hundreds of scanning electron microscope images of the tree frog’s toe pads surface and used the edge extraction algorithm to obtain the result that the geometric shape with the largest proportion in these images is hexagon. According to this result, hexagonal surface textures were added to the inner surface of the MFSA and a small part of the MFSA was taken for further simulation analysis. The flow distribution of the magnetic fluid (MF) acquired from the simulation clearly illustrates that the surface textures cause vortexes formation in the MF layer. These vortexes increase the shear rate between the MF layers, thereby augmenting the flow resistance. The vibration reduction experiments were carried out and MFSAs employed in these experiments were fabricated by 3D printing technology. Consequently, the bionic textures mimicking the tree frog’s toe pads surface can significantly improve the damping performance of MFSAs.
