  1. The problem is that bearings that are available for solidworks are not perfect models. They are somewhat lacking in detail and their materials are not defined. So If I do a simulation it has to be done (option 2) as shown in this picture. But how do I set the fixtures and forces so that the stressed lower structure behaves accordingly? How I understand it: Force is only applied downwards. As the bearing is fixed on lower face it can not translate in X- and Z-coordinate direction but can only apply force in Y-coordinate direction. But how about the wall area. Do I define it also as fi
  2. Let me throw a ball here. When doing a simulation, I can suppress the bearing. But I've been wondering if I can define bearings contact faces and say to the solidworks: "This selected face is connected to this face and should pass the force to the fixtures through this connection." Or do I just do it as: "These faces are in fixed position and pass force of N to the fixtures"?
  3. I've used Solidworks for simulation for some time, but started to wonder how to simulate two parts that are joined together by table bearing. Table bearing requires to leave a gap between two parts, but how would I simulate this in Solidworks? Let's say that we have YRT325 table bearing. Should it be excluded out of simulation between two parts and use some kind of contact plot between two parts?
  4. Thank you for the answer. Solidworks shows that the displacement along y-axel is -3.137, but I haven't calculated if it takes the beam weight into account or if the program itself calculates it using different method. I used simplified sketch with structural members in Solidworks.
  5. I've been wracking my brain with this. I would like to calculate the displacement caused by the force on beam. I've simulated this on Solidworks and then started to calculate it by hand. The problem in this is the overhanging parts that do not give the right answer when calculating by hands while compared on simulation answer. Have I typed wrong value at some point or have I used wrong values? Material is S235J2G3 and beam is HE 300B. Recommendations and suggestions are welcome.
