Abstract：To study the response and force characteristics of a human body under the impact of typical rifle three-shot burst, a skeletal muscle model of the human-rifle system with typical rifle was established.With the movement acquired by the three-dimensional motion capture system as the model drive, the inverse dynamic problem was solved.Human motions and dynamic response data in the process of shooting were obtained, which reveals the transmission and variation of shooting impact in the human body.The results show that the impact force on the right shoulder is greater than on the left shoulder, on the right elbow is larger than on the left elbow and on the left wrist is larger than on the right wrist in the whole shooting process.There is no obvious difference between the impact forces on each spine joint in anteroposterior direction.In each segmented recoil-recuperation cycle of the rifle firing process, it is found during the recoil, the impact on the joints in anteroposterior direction is greater than in the mediolateral direction, and the main joint moment is the external force moment.During the recuperation, the impact on the joints in the mediolateral direction is greater than in the anteroposterior direction, and the left and right elbows respond with flexion muscle moments.Furthermore, the quantitative change and value of the motions and exerted forces of human body key parts were presented.
