The invention provides a somatosensory motion simulation system. The simulation system comprises a user gravity center movement data acquisition unit, a standard movement model generation unit, a processing unit, a safety protection unit and a teaching unit. According to the simulation system provided by the invention, the gravity center movement data of a user can be collected in real time, whether the movement of the user is standard or not is analyzed according to the gravity center movement data of the user, when great deviation exists between the movement of the user and the standard movement, prompt is given out or the on-going movement is controlled, so that the movement behavior of the user is corrected and improved, further, the user masters the essential of the movement rapidly,therefore, the safety of the movement is guaranteed, in addition, the system has the functions of timely protection, movement body sensing and motion load generation and management, thus the user canbe helped to overcome the psychological disorder, the waist, back and leg strength is increased, and the training comprehensive effect is promoted.
