Hi~

I want to use the Ansys rocky to set the roller rotation and linear translation, but after setting the rotation center of the initial roller position, when the roller starts to move, the rotation will become a rotation around this rotation center and cannot be linearly translated. May I ask which side do I need to set to achieve roller rotation and linear translation?

Thanks!

Hello,
To apply more than one movement to a single geometry, add multiple motions to a single Motion Frame, or create a nested (child) Motion Frame and then apply the child frame to the geometry.
Alternately, you can refer them to this article in the Rocky help manual - 3.3.3.4. Apply a Motion Frame to an Imported Geometry

Hello May I ask if adding multiple motions to a single Motion Frame is as shown in the picture below? Because I made such a setting to bring the Motion Frame into the roller, after the roller moves, it will start to rotate around the rotation center of the initial roller position (-0.2185,0.2715,0.0058) and cannot be linearly translated. Even if the Relative Position is set to the origin (0,0,0), the roller will still rotate around the origin. Is there any setting I need to modify?
Thank you.
