Abstract

Three typical textures of brittle, elastic and viscous foods were selected, and the mastication was simplified into 3 modes of cutting, pressing and grinding. The optimal mastication mode of each texture was identified according to the material destruction criteria and using the finite element method (FEM). Then the mastication was set with 3 laws of uniform motion, uniform acceleration/deceleration, and uniform jerk. The optimal chewing motion laws of the 3 types of foods were analyzed via FEM. It was found at the mastication time of 0.2 s, the best failure effect of brittle foods was found in uniform acceleration/deceleration under the cutting mode, with the maximum principal stress of 6.366 MPa. The best failure of elastic foods was found during uniform acceleration/deceleration under the grinding mode, with the maximum shear stress of 15.644 MPa. The best failure effect of viscous foods was observed during uniform acceleration/deceleration under the grinding mode, with the maximum von Mises stress of 13.863 MPa. These findings will modestly guide the investigations into the motion laws of mastication robots.
