Hello all,
I am making a project on the vibrations that take place on the PHALANX CIWS during real life engagement scenarios and how the vibrations affect dispersion (barrel tip displacement).Ultimately we suggest a better way for vibrations handling.
The PHALANX CIWS, is armed with a M61A1 Gattling gun (6 barreled). It shoots in 2 paces, slow mode (3000 Shots per minute and fast mode (4500 Shots per minute).
An initial frequency analysis has been done , and the eigenfrequencies have been estimated on both 3000 SPM and 4500 SPM. Also the gun traverses from - 25 to +85 degrees vertical (eigenmodes and eigenfrequencies have been estimated in 0, -25 and +85 angles)
Harmonic and frequency analysis must follow.
Supposing the gun rotates and fires , how should the force application be modeled to capture the rotational effect scenario ? Centrifugal force has been applied to the rotor and generally all the rotating components. The barrels fire in sequence and a recoil force has been applied to the bottom of each barrel, though I am not sure if it captures the real life behaviour.
