My name is Pedro, I'm mechanical designer in Brazilian Synchotron Light Lab.
We are projecting a support for one mirror of our Infrared beam line. The support is a block with a rotational weak link which needs to be rotated about +/- 1°. I would like to know a way to insert this angular displacement and get the stress in the weak link area.
I dont have the moment loads and components.
I hope anyone can help me.
Solved! Go to Solution.
You can try using the Fixed Constraint. If you check the vectors checkbox, you can input the prescribed [x,y,z] displacement, but not rotation since the solid elements don't include rotational components.
If you have R2013 or later, and the 'weak link' geometry is considered thin, you can use Shell elements and prescribe rotations as well as displacements in the Fixed constraint command.
Hope this helps..
Best regards, -Hugh
