Bionic strips were designed and processed on the piston of BW-160 slime pump to improve its friction performance, decrease wear mass losses, and prolong service life. Nine stripped pistons were processed and manifested by different strip depths and included angles between stripes and piston surface. A workbench of slime pump piston was created to test the frictional force, oil film width, and wear mass losses. Test results demonstrated that the stripped structure can significantly decrease the frictional force on the piston. Optimal strip depth, included angle, and resistance reduction rates for stripped piston reached 2 mm, 90°, and 53.89%, respectively. The oil film on stripped piston was significantly wider compared with that of the standard piston, thus reducing frictional force between the piston and cylinder sleeve. The wear mass losses and the wear rate of the bionic piston are lower than that of the standard piston. Finally, the friction and stress of the piston are analyzed by finite element method, and the influencing mechanism on performance of pistons was discussed. The test results provide parameters for piston design of BW-160 slime pump for engineering.

“…There have been several research attempts to improve the tire profile based on the biomimetic structures; so that the tire grip can be increased and the rolling resistance can be decreased. Ivanović et al [38] have introduced two such tire productions. One of them has adopted the biology of the cheetah paw as shown in Figure 4(d), to improve the tire friction, and the other one mimicked the toe pad of the tree frog, see Figure 4(e), to improve the performance on wet surfaces.…”

Automobile engineering often demands creative and innovative concepts to achieve their performance and efficiency targets. However, the strategies used to create these concepts are evolving with time. Recently, heightened attention has been noticed to using biomimetic concepts in the field of automobile design. The studies that apply biomimicry to automobile design often exhibit improvements in vehicle performance and fuel efficiency. Consequently, biomimetic concepts have extended an opportunity to the automobile industry to generate futuristic designs with advanced technology. However, the innovations and inventions in biology are usually published with more complex terminology that is not convenient for the research community working on automobile engineering. Hence, a notable delay is present in transferring the recent discoveries in biology to engineering researches so that they can develop strategies to mimic them. The purpose of this paper is to provide a brief overview of the biomimetic design approaches that have been and can be used in automobile design. In addition, the paper includes a classification of biomimetic concepts, which reveals the current research interests and highlights the areas with a deficit of research that is required to be addressed extensively in the future.

“…In a broad sense, it can be defined as any process that artificially changes the texture of the surface. In many cases these changes are inspired by nature [1]. Defined like this, surface texturing can be obtained through some coating deposition (adding of the material) or some surface modification (without adding of the material) technique [2].…”

Surface texturing is one of the surface modification techniques which deliberately change the texture of the surface, in order to improve, among other things, its tribological performance. This is obtained through different patterns, which can be on micro or nano scale, created on the contact surfaces. The performance of a textured surface depends on the shape, geometry and pattern of the surface texture and the operating condition of the components in contact. There is a number of various techniques for surface texturing, among which laser surface texturing is most often used. The different surface texture shapes, different textured area ratios and patterns, different lubrication regimes with different contact geometries and materials have been subject of theoretical and experimental research for many years. This paper reviews the state-of-the-art of researches that consider various surface texturing for tribological application, as well as its effect on performance enhancement. Conclusions of this paper may provide guidance for optimal design of surface textures in practical engineering applications.
