Abstract Here, the gun-controlling characteristics of a shooter were studied during continuous firing. Shooters’ 15 continuous firing kinematic attitude data were captured with a 3-D motion capturing system. The human-rifle musculoskeletal model was built adopting the human body bio-mechanics modeling software AnyBody. Using the shooting kinematic data to drive the human-rifle model, the laws for muscle and joint reaction forces of a shooter were obtained based on the principles of inverse dynamics. The simulation results showed that the proposed model can better simulate the bio-mechanical characteristics of human body under recoil loads during continuous firing; the study results provide a basis for deeply studying dynamic responses of human body under continuous impacts in shooting process.
