Calculations related to the welding of container supports to the head
Thread Content
As the title indicates, I have a horizontal vessel designed with flat end caps on both sides. The supports are specified to be welded at the midpoint in the thickness direction of the flat ends; how should the saddles be calculated? For SW6, since the distance from it to the tangent line of the end cap is less than 0, it’s not possible to perform such calculations. I’m asking the experts here for help – is there any good solution in ASME or EN examples?
It’s really not easy to calculate using conventional methods; you can first carry out the simulation as required, and then use local stress analysis to verify the stress levels in the supports and the container. When checking the supports: primary consideration is the gravity of the medium when the container is fully loaded, as well as the thermal stresses resulting from the expansion and contraction of the container due to temperature changes ； When checking the container: primary consideration is the bearing reaction exerted at the weld between the side of the flat cover and the bearing ； Combined conditions of internal pressure, support reactions, and thermal stress ；
Agree with the view from the second floor; conventional methods cannot solve this problem, and local stress analysis should be used for calculation
