One of the basic requirements for the artillery weapons is the dumping of dynamical impulse loadings by the recoil system. Recoil subsystems, which are displaced during the recoiling process, have to be stopped and returned to the initial position, keeping the stability of weapon’s position. Displacement position control as a consequence of the recoiling process is an indirect performance of the recoil system design. These performances are changing vs. time gradients more or less rigid, regarding forces or displacements making recoil characteristics more or less elastic. Guides by forces in hydraulic brakes of recoil system are proportional to the recoil velocities, which are not always applicable for full control displacements profile on the weapon. Paper considered implementation of stiffness proportional linear or nonlinear to the displacement as possible variator of maximum force and their position in time for joined recoil system. As possible solution wire rope absorbers have been considered as redundant links in hydraulic brakes serial junctions. The appropriate position and variable stiffness of redundant have been considered by Bouc-Wen modified approximation redesigned for artillery gun loading profiles. Paper integrates experimental laboratory dynamic testing data with simulation software of gun recoil systems regarding the howitzer 152 mm.
