Is it necessary to calculate the supports?
Thread Content
When designing supports, do people first carry out calculations and then select the appropriate support based on those results? Our company doesn’t do any calculations; it just selects directly. I’m a beginner, so I don’t know how to make the selection. Do everyone just rely on experience?
I’m not sure which organization you belong to. Beginners should have mentors or experienced engineers to guide them; this is a requirement stipulated in the regulations for pressure vessel management. Back to the main topic, design is a process of repeated calculations. If the conditions of the equipment you are designing do not meet those specified in the standards, it is necessary to conduct verification calculations on the legs you choose
In ordinary small units, are there dedicated masters and senior engineers in charge of your every move? There are calculation examples after JB4712 \"Container Supports\"; you can take a look
Does the horizontal action point in the appendix refer to the center of gravity? How to calculate a jacketed vessel? Do we also need to consider eccentric loads for the manhole that is opened?
I never do any calculations... I just choose based on the diameter from JB/T4712...
I haven’t done any calculations either; generally, I estimate the weight of the equipment and then choose the diameter accordingly.
If it meets the standards, choose it according to those standards; if it doesn’t, calculate it on your own
Engineering companies with strict requirements demand calculations, mainly stress verification calculations. I remember that back then we worked together on creating simple calculation tables; I’ll try to find them for you when I have time
What needs to be calculated – there is a calculation method specified after the standards for the supports! ! But to save time, it’s generally fine not to do the calculations; just choose directly based on the standards!
Standard bearings have been verified under certain conditions; if a bearing remains within its applicable range, it can be selected directly. However, as long as one condition is exceeded, re-verification is necessary
It should be calculated. The legs are also part of the product.
