Help needed: design of a rectangular pressure vessel at atmospheric pressure
Thread Content
It is mainly used to hold alkaline solutions. According to the site requirements, it was designed as a rectangular atmospheric-pressure container with dimensions of 12 m in length, 2 m in width, and 1.5 m in height. It is not allowed to install reinforcement bars inside the tank; reinforcement can only be done on the outside of the tank. Due to its long length, the ratio of length to height is 1.5/12 = 0.125. After consulting JB/T4735-1997 and NBT 47003, it was found that the α coefficient required cannot be determined from the tables, which makes this design seem inappropriate for such a length. Plus, my knowledge of SolidWorks finite element analysis is only superficial, and I’m unable to obtain any results; I need help!
For the preliminary design, angle steel and channel steel are selected as the profiles respectively
Regarding the value of the alpha coefficient as specified in JB/T4735, for this design H/L=1.5/12=0.125
In SolidWorks finite element analysis, I’m not sure if the loads applied are correct; also, the coefficients in the equations were obtained from the Internet, and my understanding of them is only superficial. I hope experts can verify this
Indeed, channel steel is added on the outside; the difficulty lies in how to verify its strength
Build a 200mm thick wall around the outside using red bricks and cement, and then cover the inside of that wall with the material of your choice. Or you could just lay tiles as well. :lol:lol:lol:lol
Stainless steel: 5mm, Carbon steel: 6mm
How was this calculated? I used software to do the calculation with a plate thickness of 6 mm, and the maximum deformation amount was 16 mm
