In this study, the dynamic absorbing system for the shoulder-fired system with high-level-impact force has been investigated. for this purpose, firstly, mathematical model based on the short recoil system has been constructed. In order to design the dynamic absorbing system, parameter sensitivity analysis and parameter optimization process have been performed under constraints of moving displacement and transmitted force. In order to enhance the efficiency of energy dissipation, the stroke-dependent variable damping system has been analyzed. finally, the performance of the designed dynamic absorbing system has been evaluated by simulation with respect to the benchmark system.

The structure of the human body has a limit to absorb the high-level-impact that occurs in shoulder-fired system. In other to solve this problem, short recoil system is applied to shoulder-fired system, and is verified experimentally, and then is performed analysis of parameters sensitivity, optimization of main part. According to the results, we developed A fundamental basis for buffering structure modeling that is operated by high level input in shoulder-fired system
