Abstract : "The conventional recoil mechanism of guns provides the retarding force on the gun to stop the rearward motion in the firing cycle. The concept of the soft recoil mechanism has been developed. This mechanism was introduced to reduce the firing shock and the reaction force due to the forward momentum of the recoiling parts prior to firing. This paper verifies the theory of the soft recoil mechanism and demonstrates its feasibility on a large-caliber gun system. Numerical simulation on recoil dynamics and shock response analysis were utilized in this study. A FORTRAN program, which was developed in a previous study, was employed for simulation. The shock response analysis utilized the shock response spectrum and the pseudo-velocity shock spectrum. As a result, a newly developed recoil system was proven to be applicable for guns in the near future with further refinements."
