Friction springs have different characteristics while loading and un-loading. Because of these characteristics, they are utilized in impact systems. In this paper, the design of a recoil system with friction springs for use in a machine gun system has been presented. In order to determine the stiffness of a friction spring, equations of motion for a simple gun model with a recoil system have been derived. The impulse balance scheme has been adopted. On the basis of simulation results, the diameter of the friction spring has been determined.

A low-recoil direct gun is useful in reducing the fire impulse generated by using a traditional shell. To apply a control equation to an AMESim Model, we have formulated a control equation for a recoil mechanism from the free object diagram. By modeling this equation, we have been able to compare the recoil distance and recoil force of a low-recoil direct gun. Here, we can analyze the recoil characteristics between traditional direct guns and low-recoil direct guns with perforated muzzle brakes. It is possible to mount a low-recoil direct gun with a perforated muzzle brake on a lightweight tracked vehicle by reducing its fire impulse.
