| Abstract: | Muzzle brake accords with the dual requirements of lightweight and high mechanical properties as muzzle parts.According to this request,topology optimization was executed on muzzle brake using the finite element analysis methods,and in the groove（That material is removed） design the golden section ratio was used;using the golden section ratio in the case of the smaller mass the optimal muzzle brake had good mechanical properties and high dynamic stiffness was found by comparative analysis on finite element static strength and dynamic stiffness.The results provided reference for the structural design of the muzzle brake to reduce the impact of the muzzle to improve shooting accuracy. |
