Abstract
Many industrial equipment assemblies present internal impacts during operation. The impact and impulsive forces are characterized by large amplitude of force in a very short period of time. An example of equipment subjected to an impulsive force is the recoil mechanism of an armament. The recoil mechanism moderates the firing loads exerted on the armature support structure by prolonging the resistance time of the forces generated by the propellant gases. Basically, the recoil mechanism can be simplified by a spring-damper connected to the barrel to cushion the force exerted on the breech. This paper analyses a simplified recoil mechanism and two new models to improve the barrel response in terms of maximum displacement.
