[PSUBS-MAILIST] conical transitions

[Hugh Fulton]

Hi All,  

I have been through that problem and you have to have a good sized stiffener
there of some sort.  I could not afford the room as an intrusion of internal
space.

This is the solution and the angle of the additional reinforcing cone is
22.5 degrees being half the 45 degrees of the cone.  This survived an FEA
analysis.  The end of the cone is where my window was attached.

This was a 48" shell  .  Regards,  Hugh

Joe, ABS says stiffened cones are to have their ends bounded by two heavy
stiffeners each located as close as possible to the point of
cone-to-cylinder transition.

The stiffener is not located on the weld line but as close as possible to
it.

David,

Is that T ring directly on the weld line, or offset any distance?
