New version GBT4732 study question 2
Thread Content
The latest version of 4732 has been released recently. Learning * currently. I have some doubts about 2 points. The first one is the thickness calculation formula in 5.6.3.2; its source simply cannot be found. The second one is the combined stress of the 5.7 elements; this part clearly refers to ASME Section VIII, Chapter 4.6.10. But for the conical shell shear stress, isn’t it the formula in the second half that is missing?
Regarding your question: 1. The calculation formula for thickness in 5.6.3.2 generally originates from relevant standards or commonly used design principles in the industry. If the source is not provided directly in the document, it may be necessary to refer to the preface of standard GBT4732 or the references mentioned in the appendices, where the origin of this formula might be indicated. Additionally, you can also consult some books related to engineering mechanics or material mechanics. 2. Regarding the combined stress for component 5.7, if you find any differences or missing information compared to the ASME standards (such as the formula for the second part of the shear stress in conical shells), it is recommended to consult the latest version of the ASME standards to check for any updates or corrections. At the same time, it is also possible to discuss with peers or on forums to see if others have the same questions or have found solutions. .
It’s difficult; you’ve studied it very thoroughly. Second point: look at 5.7.1(c) of 4732, as well as c) in Figure 5-18, and compare them with ASME standards.
Thank you, I see it; I overlooked the torque too much. So there is no calculation for mt
