Reinforcement by opening holes in the cover
Thread Content
I would like to ask the experienced colleagues: apart from analytical design, what methods can be used to carry out calculations for reinforcing openings in the diagram?
Why can’t it come out from the bottom of the head and then be connected to an elbow? It also achieves the same effect as the structure in the diagram. Unless constrained by the installation location, this structure only requires analytical design; no special qualifications are needed for stress analysis. It is sufficient to use an allowable stress strength of 150. However, stress analysis of this structure can be problematic due to the numerous sharp corners and significant structural changes.
You might as well post the data; let’s see who can help you calculate it
If it’s not a fatigue condition, performing a local analysis is not very complicated either. Because partial analysis doesn’t require any special qualifications, but when you get tired of it, it costs a lot of money – after all, scarcity makes things valuable.
I’m posting the original design data provided by the user for everyone to take a look.
A pipe with diameter 159 and a short radius of the end cap of 225 is indeed excessive; installing it along the axis of the end cap and adding an elbow will increase the height of the equipment. If there isn’t enough space below, the supports can be moved. Additionally, with such a large head on this diagram, there are also issues with the boom; reinforcement bars need to be installed at the turning points, otherwise very thick rods will be required, and the stress at the connection to the cylinder body is too high. We used a similar structure last time as well; during installation, the rotating arm bent too much, making it difficult to use.
