How to determine the allowable stress of the rib plate of the ear-type bearing?
Thread Content
When the ear-type bearing is non-standard, it needs to be calculated according to the formula recommended by the standard interpretation of JB/T4712.3-2007 (P110). So how is the allowable stress determined? This is a structural part. It should not be determined based on the allowable stress of the pressure vessel material, right?

To be conservative, check the allowable stress of 150. It is not enough to consider reducing the safety factor. Check the allowable stress of structural members. The allowable stress of structural members is usually higher than that of containers. Some standards will give bending allowable stress, which is larger than the tensile strength, even up to 1.5 times.
I have seen calculation examples, which can be based on the allowable stress of structural members.
This stress needs to be calculated, and stability must be considered according to NBT47003.1-2009 Chinese Formula 7-2
