Abstract:	To reduce the recoil of high RF aerial gun and improve the firing accuracy and stability, a variable damping hole buffer device adapted to high RF was designed. By analyzing the working principle of the buffer device and designing the key parameters, a dynamic model of the automaton buffer device with friction stribeck effect was established. To reduce the recoil of the gun, the optimal variable damping hole diameter, spring stiffness and spring preload was obtained by the non dominated sorting genetic algorithm (NSGA Ⅲ), and the parameters before and after the optimization were analyzed for the comparison of the dynamic response. The results show that the maximum recoil force of the optimized aerial gun is reduced by about 19.3%, and the maximum recoil displacement is reduced by 3.7% when the aerial gun is fired in a series of stable shots, which improves the stability of the aerial gun in the firing process and provides a reference to the parameter design of the aerial gun buffer device.
