Acceleration Loadings
Acceleration Loadings
(OP)
Hi,
A customer has asked us to consider loadings of 4g in the X,Y & Z direction of a vessel supported on saddles.
Can anyone point me in the right direction with such a problem. Is this something that could be analysed by FEA or, am I over complicating the problem? Is this seismic/harmonic?
Thanks.

Obviously familiar with F=mg but where and how do we integrate this into the design, just fishing for ideas to see if we need to farm the design out or if we can do it in house.

You can consider this acceleration load analogous to transportation load case and can evaluate the vessel. Refer book- Pressure vessel design manual by D Moss.
If you are interested in the saddle to vessel stresses, above book procedure provide the stresses in saddles and vessel saddle junctions.
If interested in overall vessel stress levels, you need to do FE analysis of vessels for 4g acceleration load.
