Temporomandibular joint motion analog simulation method

The invention provides a temporomandibular joint motion simulation method, which comprises the following steps of: acquiring real three-dimensional motion data of key feature points related to representation temporomandibular joint motion, constructing a temporomandibular joint motion data set, and carrying out data normalization and preprocessing; aiming at the preprocessed temporomandibular joint movement data set, performing B spline curve fitting by means of a B spline curve to obtain a temporomandibular joint movement expansion data set; based on the extended data set, by means of the series robot, constructing a kinematic model of a temporal-mandibular joint under the series robot; and constructing a spatial position transition model of the kinematics model, obtaining an updated kinematics model of the temporomandibular joint, and endowing the kinematics model of the temporomandibular joint with a driving motor at each joint of the series robot, so as to finish simulated motion simulation of the temporo
