How to simulate a rotating expansion joint
Thread Content
In current work, when rotating expansion joints need to be selected, does anyone conduct simulations? I would like to ask about the approach to simulation. Especially the input of stiffness.
I checked the tutorial, which suggested using an expansion joint with a length of 0 to simulate this, but when I entered a value of 0 for the length of the expansion joint, the system gave an error message; it’s annoying.
Are you referring to a Gimbal Joint? If your length is 0, then entering the same stiffness value as that specified in the manual will prevent any errors; you probably missed entering it.
It’s best not to have a length of 0, as this ignores the effects of pressure and thrust; what’s the point of such simulation then?
Hello, original poster. Has your problem been resolved? ? My approach is to, when selecting an expansion joint, not input the axial and lateral stiffnesses, but only the torsional stiffness, because the thrust exerted by a rotary expansion joint is resulting from the torque generated during rotation together with the lever arm created by the rotating compensator. Additionally, a rotary expansion joint does not have any internal pressure thrust PA; therefore, only the torque and friction forces generated during rotation are involved. If you’ve solved it, can you tell me? ?
