Help! Can the design parameters of the jacket in SW6 be used for the calculation of the vacuum jacket of a cryogenic vessel?

Now the author is designing a fixed vacuum insulated cryogenic vessel, using vacuum powder insulation, as shown in the picture: That is to say, the heat-insulating interlayer between the outer shell and the inner container is filled with heat-insulating powder. The problem now is: 1. Is the jacket body design in the body design parameters in SW6 applicable to the calculation of the thermal insulation interlayer in cryogenic vessels? 2. Are jackets and vacuum jackets in cryogenic vessels the same concept? Welcome all Haiyou guidance! !
Really? ? ? Are jackets and vacuum jackets in cryogenic vessels the same thing? ? ?
No, this needs to be manually modified and calculated.
Not applicable, Cryogenics has corresponding calculation standards.
Same. It’s just that the jacket layer has negative pressure. Commonly used jackets are pressurized. Vacuum cryogenic containers must also comply with GB150, but there are special requirements in other aspects.
What's going on? Has anyone designed a cryogenic container? Can you give me a design tutorial or something?
I have never done cryogenics, but I am interested in how to make this.
I have never done cryogenics, but the relevant cryogenic standards should have more requirements in terms of material selection, manufacturing and installation. The basic theory of strength calculation should be consistent with conventional pressure vessels. Therefore, under this general principle, since vacuum is mentioned, I personally think that the calculation should be considered based on external pressure.
