Progress in the bionic study on anti-adhesion and resistance reduction of terrain machines

Abstract

The theoretical studies of bionics of machinery have great scientific significance, and the development of bionic machines has large practical values in the field of engineering and technology. Through the rigorous selection process of evolution, the survived living organisms have successfully developed outstanding abilities to adapt to their surroundings and to reproduce their offspring. In this review, we interpreted the fundamental principles of anti-adhesion and anti-resistance of soil animals by reviewing the current status in this research field and summarizing the work of the research group at Jilin University of China in the past decades. The principles and technologies used in morphology bionics, electric-osmosis bionics, flexibility bionics, configuration bionics and coupling bionics were examined. Finally, the applications of the engineering bionics and their extensive prospects were introduced.terrain machines, anti-adhesion and anti-

Bionic design methodology for wear reduction of bulk solids handling equipment

“…(Ren et al 1995;Ren et al 2002;Ren 2009), the back of ground beetle (Ren 2009), and a pangolin scale (Tong et al 2000). These three surfaces have convex domes, concave pits, and corrugated ribs, respectively (Ren et al 1995;Tong et al 2000;Ren et al 2002;Baumgartner et al 2007;Tong et al 2007;Gao et al 2008;Liu et al 2008;Rong 2008;Zhang, Lu, and Li 2010).…”

Figure 2 Unlike engineering product surfaces that interact with the particulate solids, these biological wear-resistant surfaces have non-smooth morphologies with a variety of discrete elements (Dai, Tong, and Ren 2006;Arvind 2008;Ren 2009). These non-smooth surface morphologies form various biological structures which have an important impact on their wearresistant abilities (Vincent et al 2006;Tian et al 2010;Zhang, Lu, and Li 2010).…”

“…Bionic design is an innovative methodology which utilizes biological characteristics to improve the abilities of modern engineering products or systems (Ball 1999;Vincent et al 2006;Dai, Tong, and Ren 2006;Arvind 2008;Ren 2009). For example, by using the biological wear-resistant morphologies from dung beetles, the wear-resistant ability of agricultural (Chirende and Li 2009) and drilling instruments (Gao et al 2009) can be enhanced.…”

New advances in biomimetic surface

“…From the perspective of surface type, there are two typical anti-adhesion mechanisms: micro-and nanosurface structures and liquid-covered surface. Many living organisms possess one or two of these anti-adhesion surfaces in order to achieve superior anti-adhesion, for example, soil animals like mole cricket and earthworm [1]. Carnivorous pitcher plant Nepenthes can capture and digest insects to meet the fundamental nutrients needs.…”

Fabrication of a micro-structured surface based on interfacial convection for drag reduction

“…Among the wide ranging techniques for drag reduction, surfaces with specially designed structures, such as lotus-like ultra-hydrophobic surfaces [1][2][3], shark skin-like micro-structured surfaces [4][5][6][7][8][9][10][11][12][13][14], and other bionic non-smooth surfaces imitating living organisms in the natural world [15], have been established through numerous experimental and numerical simulation studies. In these studies, however, designed surfaces are manufactured by traditional mechanical methods [4][5][6][7][8][9][10], such as milling, turning, rolling and embossing, or using riblet films [12][13][14].…”
