The invention belongs to the aircraft structure protection field and relates to a vibration reduction device for weakening the energy impact of an aerial gun muzzle. The vibration reduction device comprises a main body structure (1), a connection structure (2), a flexible structure (3) and a reset elastic structure (4); the main body structure (1) is an integral structure and comprises three sections; the connection structure (2) comprises two metal rings which are formed by memory alloy and sleeve a gun barrel (21); the flexible structure (3) is a cylinder, wherein the third section of the main body structure (1) sleeves the cylinder; one end of the reset elastic structure (4) is connected with the flexible structure and the other end of the reset elastic structure (4) is connected with the inner wall of the main body structure so as to pull the flexible structure back to the original position. According to the vibration reduction device for weakening the energy impact of the aerial gun muzzle, the impact energy of the high speed gas after an aerial gun shell leaves a gun bore can be weaken and the damage of the impact energy to the structure around the gun muzzle can be reduced.
