Abstract: Serial and parallel combination of wire rope absorbers junctions provide better absorbing of shock forces and external impulses. This performance is acceptable to be taken for different purposes including recoil force dumping. Paper considers relations of deviation caused by nonlinearities and hysteretic behavior as consequence of absorbing energy dissipation. This hysteretic behavior orientated threshold displacements required in application of this system to be employed in the design of composed hydraulic and wire rope weapon barrel brakes and recuperators. Main experimental parameters represented differences of mentioned serial and redundant junctions. Performances are estimated based on experimental static tests realized in this paper. Attempt of comparison with ideal elastic model is also performed.

Key words: wire rope absorber, hysteretic, serial and redundant junction.
