ANSYS Workbench: revolute joint problem

Click For Summary
The user is experiencing issues with a revolute joint in ANSYS Workbench during a structural static analysis, where object 2 is intended to rotate around a joint with object 1 but behaves like a fixed joint. Attempts to use frictional contact instead allow object 2 to follow object 1's movement and rotate when in contact with object 3, but it fails to rotate when not in contact. The problem was ultimately resolved by correcting the reference coordinate system, specifically the Z axis. This highlights the importance of ensuring accurate coordinate systems in joint definitions for proper functionality. The discussion emphasizes troubleshooting techniques in mechanical modeling within ANSYS Workbench.

Hey folks,
I am doing a structural static analysis in ANSYS Workbench. A problem has troubled me for several days. Here it is: I would like to connect object 2 to object 1 by a revolute joint, which allows 2 to follow the movement of 1 and to rotate around this joint at the same time (under the effect of a spring pressed on 2, and the effect of an object 3 which is initially in contact with 2). The revolute joint is correctly defined, but it works as a fixed joint, which means 2 follows the movement of 1, however it cannot rotate around joint axis as defined.
I tried another method to create the model, by replacing the revolute joint by a frictional contact between the cylindrical surfaces of object 1 and 2. When object 2 is in contact with 3, the model works well (2 follows the movement of 1, and it rotates). However, when object 2 is no longer in contact with object 3, it moves but doesn't rotate.
Do you have any ideas what is wrong in my model? How could I realize the connection? (by revolute joint or frictional contact)
Thank you in advance.

Solved! I didn't check the reference coordinate system. The Z axis was wrong.
 
Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
