    advanced fixture problme

    Werther Zhou

      Hi all,

      I want to simulate a beam which is fixed at one end and rotates along the transverse axis at the other end, like the picture below.c1.png

      How to set the rotating fixture? There is no such options there.

      Thanks very much!!!

          You can use the split line function and advanced fixture to create a "pinned-end". This little video from GoEngineer shows one way to do it:

              Dear Anthony,

              Thank you very much! The video gives me much information, but I do not think it solves my problem.

              I want to simulation the situation that one end of the beam rotates and keeps being a plane, but the advanced feature only gives two along directions and on normal direction, no rotation option. Can not the solidworks do the job?

              best

                  Yes. You only need an edge or a split line. This way, the nodes will line-up along the split line. If you apply dir1, dir2 and dir3 =0 along the split line, the body will be able to rotate around the axis of the split line. I hope that helps!

                      Hi anthony,

                      Yes, I got your point and I can repeat what you said. But after I define the advanced fixture, I should define a force to make the object deformed, am I right? However, what I intend to do is just use two fixtures, one end fixed and the other end rotating a small angle but still keeping in a plane, to see its deformation. Can I realise that situation?

                      Thanks very much!!!

                      best regards

                          Sounds like you want to be using the Remote Displacement (External Load -> Remote Load/Mass...) rather than a fixture to achieve that, if I'm understanding correctly.

                           

                          Simply set the centre of rotation in the middle of the face you want to move, have null translation values and specify your rotation value.  This then moves the face but keeps it (almost perfectly) planar.
