Circular flat lid
Thread Content
As shown in the figure, can this structure be simplified to a circular flat cover, with the thickness designed using the formulas in GB150?
Calculating based on a flat cover results in an overly conservative figure; I wonder if there is a better method
Calculating based on a flat cover results in an overly conservative figure
My job is to thin things out and reduce their weight
I’d like to ask how you knew it was a conservative approach. I’m wondering: if you know that this method is conservative, then you must also be aware of methods that aren’t conservative. I’m truly seeking your advice
Finite element analysis is carried out using solid modeling, and evaluation is conducted in accordance with the \"Steel Pressure Vessels – Code for Analysis and Design\" standards; a thickness of 30 mm is sufficient to meet the requirements； A circular flat cover model was used to calculate a thickness of 36 mm ； The actual machining size is 35 mm, a value provided by the designers based on standard flanges.
What software is used for finite element analysis? Is it recognized by the Evaluation and Bidding Committee?
I use ANSYS because it is for linear elastic analysis, and the differences among finite element software have little impact on the results. The use of finite elements is described in Appendix K of the \"Steel Pressure Vessels – Code for Analytical Design\".
