Abstract As the control factors of the shooter have a significant impact on the firing stability of the weapon in shooting process, in order to study the impact of the control effect of the shoulder and waist on firing stability of a grenade launcher, a man-weapon system model with shoulder supported was developed. According to the characteristics of the shooting, the human body and weapon were simplified to two rigid bodies with five degrees of freedom. The acting forces on the shoulder and waist were simplified to the effect of equivalent springs and dampers. Simulating with different values of equivalent parameters, the results show that different controls of the human body have different influence upon the firing stability of weapon. The equivalent parameters of the waist and the pitch damping coefficient of the shoulder are critical for the design of the firearm mount.
