Dear Members,

How to Model an fully articulated bellow in Caesar?

Thanks in advance.

Use the expansion joint modeller and read the relevant sections of the Caesar II User Guide before you do anything else.

Thanks.. but I already did the Tied Bellows Expansion Joint - Complex Model with the stiffness from a popular vendor catalogue in Caesar. When I send those stiffness values to the vendor, he came back with the fully articulated bellow. So I googled to find out, how exactly was its profile. To my surprise it was the same as the Tied bellow, except it had two seperate sets of convolutions with a piece of pipe in between.

If anyone, have the idea of how to model a fully articulated bellow. Please present your ideas.

Also increasing the tie-rods diameter, varies the results. As I work with 18" line, I increased the tie-rods from 1" to 3" dia which made quite a difference with the results. Pls advice.

Thanks again..
