Transient Structural – Joint locked

[William D.]

Hello, I encountered the problem from the screenshot, which is that when simulating a revolute joint, it rotates at a small angle, then stops and the body - support begins to deform. Nothing limits the joint along the tangential axis. The steps in the analysis settings are given quite smoothly. As a joint load, I set a smooth rotation of 90 degrees. I tried to set joint load to moment, but the problem is still the same. Material is default (structural steel). There are no degree limits on the hinge itself. Replacing it with other values ​​did not help. Please tell me what to do. Thanks in advance.

After trying to improve the mesh and add a moment load to the joint, the joint itself began to rotate a little, but at the same time it began to be flattened in all directions, and the upper side of the cube at the hole began to rise towards the shaft.

Hello,

You can provide Stops in Joint object Details view properties. These can be entered as RZ min and RZ max in angular values.
