Investigation of Human Masticatory Movements Using ADAMS and MATLAB/SIMULINK


Article Preview

A jaw mechanism based on the biomechanical findings of human mastication system is being developed to simulate jaw motion and investigate its effect on jaw function to provide the basis for jaw model. Following an investigation into the biological process of mastication, a linear cylindrical actuator is used to replace a group of muscles, and it can act bio-directionally with both origin and insertion attached to the skull and the mandible via spherical joints. The trajectory of the incisal point can be reproduced through programming the six actuations. So it builds the functional `relation between incisal point and six actuators. Co-simulations for motion and control have been conducted using the ADMAS and SIMULINK and the results have indicated that the jaw mechanism enables the jaw behaviors to be reproduced perfectly.
