How to perform strength calculations for horizontal containers with jackets
Thread Content
This post was last edited by gn_1984 on 2015-8-10 at 15:13. According to the NB/T47042-2014 standard, structures that are not applicable to this standard are containers with jackets. Has anyone worked on horizontal containers with jackets? How should such structures be calculated? @huandong @humanrzm @gjyzb @FORREST_GUMP
I don’t know how to handle it either; I encountered a similar case before, and I just did a rough calculation by treating the inner cylinder as the load and considering the jacket in the calculations.
Wow, that’s so difficult; I never even thought about it. I’ll start by learning *that*. Whether I can understand it or not is another matter. I know nothing about mechanics or anything like that, but I really like hearing you use mechanics to analyze and solve problems. The first person I think of when I encounter difficulties is you. When you have time, come by more often so we can all exchange ideas and discuss together.
Learning is endless. For strength calculations, the worst-case scenarios should be considered: the pressure inside the jacket and the pressure inside the vessel.
Only analysis and calculation can be done using Ansys
There’s no other way; one has to combine vertical and horizontal calculations, otherwise what else can be done but analyze it?
The Geng version – I’ve never seen this before. If you’ve done the calculations, please share them so that everyone can learn from them :)
Solve! I encountered a similar situation recently as well. . . How do I calculate it! ?
It’s quite difficult, unless the jacket section is misaligned with the seat; efforts should be made to meet the standard model for horizontal containers.
It should be difficult to use the NB/T47042 formula, as the sectional moment of inertia for beams according to this standard is calculated based on a single-layer cylinder, whereas the bending stiffness of a double-layer cylinder is definitely greater than that of a single-layer cylinder. As for the local stress at the supports, I think it can be used as a reference.
