Hello, CAD mode errors have been treated and now it is time for simulation runs !
I am modeling the behaviour of the shock absorbers of the PHALANX CIWS during operations in three scenarios , one shot , a burst of 100 shots and finally a 1500 shot burst (runing out of ammo scenario).
A frequncy as well an harmonic and dynamic analysis must be done.
I would like some advice / guidance on the following 
-
The modeled M61A1 Assembly has an eighteen double row angular contact ball
bearing and a needle bearing of 36 rollers that hold the rotor shaft. Is there any way to model the bearings counterclockwise movement ? (Till the moment i have applied centrifugal foce on rotating parts and the corresponding sliding contacts) -
In the firing scenario projectile recoil force has to be taken in consideration, on the single shot i guess that applying the force on the firing barrel bottom as well as the corresponding face of the rotor locking lug is enough, but what happens in the 100 and 1500 burst scenarios?

The 4 hydraulic shock absorbers are initially modeled as a male and a female piston getting seperated with an elastic support , after getting the measurements on the absorber force that is applied on the pistons faces we are going to examine a hydraulic shock absorber
The overall concept is studying the shock absorbers distribution on gun dispersion at the 75 Hz frequency (resonance risk - gun rotates at 4500 RPM)
