    FEA problem - Need help with simulation

    Vegard Tveit




      I am currently sitting with a model of a robot i am planing to build for a project at school. It has been a while since i have used SolidWorks and i have never really used the FEA part.


      I am trying to simulate stresses and the deflection when a force of 500N is applied to the tool part of the robot. But i keep getting errors in SolidWorks when running the simulation. I know that something is not properly defined and would like if someone with some knowledge in the field could give some guidelines/tips on how i can get this simulation running?


      I have made a version with the tool modeled up very basic and one that is close to what we want (without the belt system and motor)






      If the links doesn't work, the SW files are attached in zip files.


      Every tip will be greatly accepted as I learn more and more.

          There are many contact sets missing in this simulation.

          I have learned not to rely on the global contact set for components that are not touching with a surface to surface contact.


          I would start with each of the parts in your assembly and create contact sets on all faces that interact with the next part.

          If you start with the "base_firkant" and work your way to the tool you can be sure you don't miss anything.

          Sub assemblies should behave as a solid part.


          You should probably reduce your mesh size also (54mm is pretty big).
