Abstract
This paper describes mathematical and mechanical models that simulate the nonlinearity of the human masticatory muscle. In addition, the experimental results of a real food chewing experiment by a mastication robot is described. When the lower jaw rapidly closes during the chewing motion, it may come in hard contact with the upper jaw if the food is a crushable one. To clarify the mechanism of this reflective jaw motion, the authors focused on the nonlinearity of the human masticatory muscle. The authors propose a feasible mathematical model of the muscle and its nonlinearity. A nonlinear viscoelastic mechanism is designed based on the mathematical model. As a result of chewing experiment, the authors confirmed the effectiveness of the proposing mechanism for the control of the robot jaw.
