挖掘机仿生斗齿土壤切削试验与减阻机理研究
Experiment and Drag Reduction Mechanism of Bionic Excavator Tooth during Soil Cutting
摘要
Abstract
A bionic excavator tooth was developed, which is bio-inspired and based on the morphology of the toe of mole cricket foreleg claw. The profile line of the mole cricket's toe was fitted by using polynomial fitting method. The bionic tooth specimens were fabricated by a rapid prototyping machine. The cutting resistances of the bionic tooth and JL80 tooth specimens were measured during soil cutting. The experimental results show that the cutting resistances of bionic tooth is about 11 % lower than that of JL80 tooth. The force analysis indicates that the bionic tooth is more likely to form self-sharpening blade so that the cutting performance of the tooth can be maintained. Besides, the bionic tooth is convenient for reducing the cutting angle, which can help for the reduction of cutting resistance, without changing the design and working condition of the excavator.关键词
