I am modelling individual bellow elements for a press. bal. exp.joint by three methods.
1)inserting axial and lateral stiffneses
2)inserting axial and angular with zero length of bellow
3)inserting axial and angular with with non-zero length of bellow
The results(loads on adjascent equipment nozzle) by three methods differ substantially in lateral direction.
What may be the cause of difference in results and which is the recommended method?
Caesar calculates transverse stiffness for non-zero bellow element, where this calculated value appears.
What is the equation to calculate overall lateral stiffness based on individual stffness.
Thanks,
Rocky
