How to simulate uniform internal pressure on a conical shaped vessel

[andreotti60]

Hello folks. 

I hope to avail myself of your collective wisdom and experience with a particular challenge I face.  I have designed an air reservoir in Fusion 360 and I would like to simulate uniform pressure on the entire inner structure to determine whether this specific design and its concomitant specifications can theoretically sustain to be pressurized to 800-900 Psi given the size of its shell and tensile strength of the material used, namely Polylactic Acid (PLA) plastic with a rating of 37 MPa (370 bar).

I have located some discussions on this general topic, but these discussions usually center around a sphere.  My problem involves a conical shape.  Not being a structural engineer (my father was one but unless I use a Ouija board to speak to the dead, he is unlikely to help me), I hope you can.

Many thanks!

Hello Gianluca,

Hopefully this links will help and or guide you to solve the pressure on a conical shape tank.

An easier way to solve this would be to use the Simulation module in F360 and perform a Static Stress Analysis. However, you will need to have all the necessary material properties required by the FEA solver.

There is a Quick Tip in the F360 Blog that might help :  https://www.autodesk.com/products/fusion-360/blog/making-the-most-of-simplify-in-the-fusion-simulati...

Hope this will help you.
