Abstract:
In order to study the influence of the barrel deformation and vibration to the fire density of the gatling gun fire on the light tripod,a rigid-flexible coupling multi-body model is established through ADAMS,and the dynamics and kinematics of the system are simulated.Ignoring the influence of the soil deformation,the fire density and the deformation of flexible bodies of the gatling gun on two different structures tripods are compared.When an arc-shaped support plate tripod is adopted,the deformations of the barrels and the tripod of the gatling gun decrease significantly,and the radius of 70% scattered circle is reduced 35.7%.The results show that the deformation of the bottom carriage and the rotation of the upper carriage enhance the barrel deformation and muzzle vibration,the arc-shaped support plate can reduce the tripod deformation effectively and raise the fire density.
