SW6-2024 Component Calculation
Thread Content
When calculating the flanges of components using SW6-2024, the calculation report generated shows that arbitrary flanges are calculated as integral flanges； When using the SW6-2011 software to calculate container flanges for components, the resulting calculation report treats any type of flange as a loose-flange type flange ； The calculated effective thickness of the container flange has decreased.
The reason for this difference is that SW6-2024 and SW6-2011 use different calculation methods when dealing with the components of container flanges: - SW6-2024: Calculates any type of flange as a single unit. For integral flanges, the overall stiffness of the flange and the cylinder usually needs to be taken into account, which results in more stringent calculation conditions and thus a relatively larger effective thickness for the flange. - SW6-2011: is calculated based on a loose flange. This calculation method assumes that the connection between the flange and the cylinder is relatively flexible, ignoring the effect of overall stiffness; as a result, the calculated thickness tends to be on the low side. Therefore, it is normal for the contents of the calculation sheets to differ between the two versions of the software due to differences in the calculation models, which results in a decrease in the effective thickness of the flange. The actual design should be based on the latest regulatory requirements as well as the specific conditions of the project. .
I think you have it exactly backwards. When any flange is treated as a integral flange, its stiffness is provided jointly by the flange plate and the cylinder. When any flange is calculated as a loose-flange type, the stiffness of the flange is provided only by the flange plate itself, with the cylinder not contributing to it. Therefore, the thickness required for the overall flange is smaller.
Agree with the opinion on floor 4! Actual verification also follows a reduction in the overall flange thickness.
