中文摘要:

The effects of biomimetic designs of tine furrow opener surface on equivalent pressure and pressure in the direction ofmotion on opener surface against soil were studied by finite element method (FEM) simulation and the effects of these designson tool force and power requirements were examined experimentally.Geometrical structures of the cuticle surfaces of dungbeetle (Copris ochus Motschulsky) were examined by stereoscopy.The structures of the cuticle surfaces and Ultra High Mo-lecular Weight Polyethylene (UHMWPE) material were modeled on surface of tine furrow opener as biomimetic designs.Sevenfurrow openers were analyzed in ANSYS program (a FEM simulation software).The biomimetic furrow opener surfaces withUHMWPE structures were found to have lower equivalent pressure and pressure in the direction of motion as compared to theconventional surface and to the biomimetic surfaces with textured steel-35 structures.It was found that the tool force and powerwere increased with the cutting depth and operating speed and the biomimetic furrow opener with UHMWPE tubular sectionridges showed the lowest resistance and power requirement against soil..
