I have a question about the displacement load of Caesar
Thread Content
At the pipe connected to the device’s outlet, a displacement load is applied during simulation to represent its connection to the outlet. How is this displacement load determined?
Why isn’t anyone replying? Could it be that my question wasn’t clear enough :(
It is the expansion displacement of the equipment; for specific calculations, refer to page 4 of Tang Yongjin’s book \"Stress Analysis of Pressure Piping\".
5# Stars on a Rainy Night: Your understanding is correct; generally, the center of the bottom of the tower is used as the fixed point.
6# Stars on a Rainy Night: Generally, there should be stars in three directions, depending on the relative position of your nozzle and the fixing point. Note that if you fill in the displacement table, the angular displacement should be set to 0; otherwise it is assumed to be free.
Simulating the effect of equipment expansion on the pipes connected to it by applying displacement loads is, in itself, a simplified method of simulation. The direction of the displacement loads can be determined depending on the circumstances; for example, if the tower has a small diameter and is tall, with the pipe outlet located at the top of the tower, then the axial expansion at the pipe outlet will be significant while the lateral expansion will be minimal. In such cases, the lateral expansion can be ignored, and only the axial expansion needs to be taken into account. When it comes to stress analysis, I am also just a beginner; the above are merely my personal opinions. If there are experts out there, please feel free to offer your guidance!
Oh. The angular displacement values must also all be 0
