Angle between the coordinate systems of the nozzle and the cylinder in the local stress calculation of SW6
Thread Content
As shown in the screenshot, when calculating local stress, which angle exists between the two coordinate systems, and how should it be determined?

I think what is meant is whether the direction of the actual loading force coincides with the direction of the force shown in the diagram; if they don’t coincide, what is the angle between them. The software then breaks down the force into two forces that are in line with the directions shown in the diagram, based on the angle you enter, and proceeds with the calculations. But generally, the direction of the loading force is the same as that shown in the diagram, so entering 0 should suffice. I’m not sure if I understand correctly; I’ve always entered it this way.
I think so too, but I haven’t calculated it and I’m not entirely sure
Basically, in every calculation we do, it’s assumed that the load is applied in this direction; we haven’t encountered any situations where there’s an angle involved yet.
@Paris: We use pipes of this type, with a flat welded pipe plug at one end and a flange on the other side
May I ask, how are the radial force, horizontal force, torque, and bending moment calculated?
I understand it as the angle between Axis 1 (the coordinate system established based on the force) and the x-axis (the coordinate system established based on the cylinder). The z-axes of the two coordinate systems coincide; generally, in calculations, these two coordinate systems are made to align with each other, and the angle entered is 0
