Abstract

ABSTRACT
Paper considers model of shock loads dumping during launching by using the wire
rope absorber. Loadings are generated and initiated by shock forces, appeared as
reaction of nozzle gases at muzzle velocities conditions on the Multiple Launch
Rocket System (MLRS). Dumping of impulse loadings could be realized by design of
wire rope absorber tested and represented in this paper. Absorber is typical
nonlinear, no periodical dumper. Experimental model of absorber is tested by
equipment able to simulate approximations of real launching forces. Different short
time dynamical loadings are approximated with linear and harmonic functions as
initial shock and unsteady forces. Relations between initiation shock forces and
response forces at the exit of wire rope absorber are compared experimentally by
results tested in real time. Results presented in the paper shows force-time
performances and possibilities for application of new ring designed of wire rope
absorber used at MLRS combat platforms.
