  Hi Peter, useful information! I have a question about definiting beam connectors: would it be right choose the lower hole with a pinball radius for the mobile scope (as you did for the reference scope)? If is better do it as you did in the video, if you would have more than two plates, you should chose the inner hole of all of them for the mobile scope? Hope your answer! thanks

  Hi Marina, when a bolt clamps 3 plates together instead of 2 plates as shown in this video, the middle plate has a clearance hole and is held in place by frictional contact with the top and bottom plates. The bolt does not interact with the center plate at all. This assumes that the clamping force of the bolt and the coefficient of friction are high and the shear force on the middle plate is low so that it does not slip. If that is not the case, then I would add frictional contact between the side of the bolt and the middle plate hole to support the middle plate shear force on the side of the bolt after the parts have slipped. Generally, joints that allow slippage are unacceptable with rare exceptions.

  OK...I've set up the analysis exactly the same way in Nastran (but many more tet10 elements) but I'm getting wildly different results - max deflection 0.82mm, the stress field is pretty much the same but the values on the bolt itself are very much higher - max 2100MPa. Others?

  Ok...Two things...1 - My hug stress level is a singularity due to the way I need to apply preload in Nastran. 2 - The author has shown X-axis directional displacement instead of Total displacement. My Nastran outcomes align nicely now. Fields looks similar, however displacement calues are a bit different in X direction, range = -0.16 to +0.0187 compared to author's -0.1 to 0.023

  When I model a bolt preload for a bolted joint, I generally don't look at the stress in the bolt because I idealize the bolt leaving a sharp interior corner that creates a singularity. I use a separate Excel spreadsheet for bolt stress calculations. The Ansys model is used to evaluate the stress in the two parts that are being loaded after being bolted together.

  Use DesignModeler to build geometry where a parameter can reduce the body to a size that is smaller than the location where the hole exists, and have the hole reappear when the parameter increases the body to a size that includes the location of the hole.

  I recently found that in a multi bilted joints, bolt load distribution is not even. How to take that into account

• 
  @ansysfeaexamples93516 ай бұрын

  Apply separate Bolt Preloads to each bolt. Apply the same value of preload to each bolt in step 1. Apply some other load to the structure in step 2. Add a Bolt Probe to the Solution section of Mechanical. There you can output the Working Load for each bolt to see the individual loads carried by each bolt, which could be different. You could also put a Contact Tool in the Solution branch and plot the Contact Pressure in the interface between the parts. You may see higher pressure around some bolt holes and lower pressure around other bolt holes.

  Question here sir, I’m doing the same test with a formula SAE chassis for my college team. I’m also not getting any stress as the original ANSYS forum poster. Another issue I have is I have random tubes coming free and just floating after impact. I did my geometry in designmodeler and have shared topology along edges. Is there anything else I should look at to ensure the tubing is actually constrained and “welded”?

• 
  @ansysfeaexamples93517 ай бұрын

  To check that the tubing is constrained, drag and drop a Modal analysis onto the Model cell of your first analysis. In the Modal analysis, add fixed supports to some hard points in the frame, request at least 12 modes under Analysis Setting and solve. Add 12 deformation results for the 12 modes. Any tube that is not properly connected can be seen floating around or one end may be swinging around in one of the modal results. If you built your tubing with beam elements, instead of shell elements, you will need to insert a Beam probe into the Solution branch to plot beam stresses. For more help, post a question in the General Mechanical section of forum.ansys.com/

  Hello Peter, thank you for the tutorial. I'm facing an issue with the autoskin tool. When I upload my stl file (which is a vascular network generated with Matlab), I have a faceted body similar to yours with lots of facets, however, when I go to autoskin it actually turns into a solid body but the number of faces remains pretty much the same (hundreds of thousands) so it is completely unmeshable, what can I do? I already tried to use the "merge faces" tool but it takes to long or simply it does not work all over the body. Thank you in advance.

  Hi, When i'm trying this, the initial analysis works. However, when I update the geometry using the table, the fixt constraint is removed from the analysis and i have to manually redefine it. Any thoughts on how to solve this? Regards

• 
  @ansysfeaexamples93518 ай бұрын

  Hi @baslord88, it may be that the design study parameter causes the surface to which the fixed support was scoped to be consumed in the shape change driven by the table. Go to forum.ansys.com/ where you can join for free. In the General Mechanical channel, Start a New Post and insert screen snapshots of your geometry and show how the parameter changes the shape. It will be easier to have a discussion on that forum.

  Yes, it is possible to have cartilage between the bones. It is simply a matter of having the CT data segmented for cartilage instead of bone, then convert the STL into geometry. Ligaments are sometimes represented as springs.

  The formula you show is for Euler beam theory. Ansys uses Timoshenko beam theory in their beam elements. If you use a Timoshenko beam theory formula, you will get the same answer as Ansys. Or you can use an obsolete beam element that uses Euler beam theory then Ansys will match the answer you got.
