Design and Experiment on Bionic Chewing Equipment

Abstract:

A bionic chewing equipment was developed for food breakdown by simulating the masticatory system and using the bionic technology. Some parts were designed and assembled by reverse engineering method, like bionic teeth and temporomandibular joints. The equipment could realize 3-D chewing motion, the movement parameters were determined. Test of occlusive force showed that chewing force of equipment could break food and change with food. Masticatory experiment showed that masticatory efficiency of the equipment had no significant difference with subjects and its maximum value was 92.3%. The bionic chewing equipment was stable and reliable.
