Abstract: In order to reduce the soil wedging resistance, a bionic excavator bucket teeth was designed based on the JL80 excavator bucket teeth by applying the configuration information of mole cricket foreleg claw. The samples of bionic and JL80 tooth were fabricated by a rapid prototyping machine. The relation between wedging resistance and displacement was measured by wedging experiments using a testing machine. Moreover, the wedging processes of two kinds of excvavtor tooth were numerical simulated by finite element analysis software. The results show that the wedging resistance of bionic bucket teeth is 11% less then that of JL80 bucket teeth under the same experimental condition. The results and conclusions can provide references for optimization design of excvavtor bucket teeth.

Key words: bionic engineering, engineering machinery, excavator bucket teeth, mole cricket, numerical simulation
