Experimental Structural Analysis of Pedestal Mounted Stinger System Turret

An experimental approach for the solution of the turret stress state and dynamic behavior has been presented using strain gages and accelerometers on Pedestal Mounted Stinger System. The critical stress locations were determined by finite element analysis outputs where rosettes are bonded in order to perform the life profile simulation tests. The fatigue state is determined by cycle counting methods used in data processing of the turret launcher connection zone. The lowest disturbing frequency of the turret determined from the operational tests is further investigated by the experimental modal analysis. Consequently, the servo drive system is operated efficiently after design modifications applied to the turret.
