Surface Structure Research and Design of Drum's Coating Layer Based on Bionic Tribology

Abstract

. The slippage often occurs between conveyor belt and driving drum, reduces the transmission efficiency and even causes accidents due to lack of enough friction. By the analysis of friction drive principle in belt conveyor, three ways were presented to increase the frictional traction. Learning from the bionic tribology theory, we proposed a new structure design of the drum coating layer surface. The micro contact area of fly's seta that can adhere to any surface was taken as a prototype, and its microscopic structure was analyzed, then the surface structure of coating layer with recess long blocks was designed, finally, the solid modeling was created with CAD software. The new surface has sub atmospheric pressure absorption. The purpose is to increase the friction between conveyor belt and driving drum, and to avoid the slippage.

Stimuli–Responsive Mechanoadaptive Elastomeric Composite Materials: Challenges, Opportunities, and New Approaches

“…Mechanoadaptive elastomeric materials can be used for smart tire application. The change in the size of the contact area as shown in Figure 13f can adapt to the wet, slippery, dry, uneven, as well as smooth surfaces [223][224][225][226] and will contribute to better rolling resistance as well as dry or wet traction depending on the environment, climate, and road conditions and will be useful in all seasons. This will reduce the replacement cost of tires and the same can be utilized in summer, rainy season, or winter, whatever the case may be.…”

Study on the Magnetic Field‐Dependent Rolling Friction Coefficient Compensation of Magnetorheological Elastomer–Copper Ball Friction Pair with Wet Interfaces

“…It is an important way to increase and adjust the coefficient friction using surface structure designs and additives. For example, Sun [ 2 ] designed a convex shell driving a drum with a friction increasing effect, Xiao [ 3 ] designed a coating surface friction increasing structure with grooved long blocks, and Mabuchi [ 4 ] discussed the effect of additives on increasing the friction coefficient of the film interface. Marvi [ 5 ] proposed a technique for active control of frictional properties of fibrillar structures.…”
