Abstract: Based on the feelings of shooter during shooting, the gun recoil, recoil pressure, impulse of gun acting on shooter, and the acceleration, velocity, displacement of shooting are analyzed. The evaluation factors and evaluation function of sensible gun recoil are ascertained, and the evaluation concept of sensitivity threshold and sensitive recoil impulse is proposed by the method. A new multi-factor evaluation method of sensible gun recoil is proposed. The recoil physical quantity characteristics of Type 79 and 85 submachine guns are analyzed. The analysis result shows that the evaluation method could comprehensively and quantitatively describe the strength of sensible gun recoil.
