ANSYS Help Needed: Modeling Standard Straight Gate Karabiner

[Barn-Unit]

I'm trying to construct a model of a standard straight gate climbing karabiner in ANSYS so that I can evaluate the maximum tensile load applicable. The trouble is that I am, to put it plainly, failing.

The karabiner must be modeled in 3D and I am going to be using a SOLID95 element type, as stated by the design proposal.

I have measured the karabiner and input the necessary keypoints and lines but when I try to use the VDRAG command the cross-sectional area does not drag correctly, leaving a gap between where the drag started and finished. I have tried everything I can think of to remedy this and have altered the geometry numerous times with absolutely no luck.

If anyone can shed any light on this problem or give any advice it would be greatly appreciated as I am facing a tight deadline.

Thanks in advance.

I understand your frustration with trying to construct a model of a standard straight gate climbing karabiner in ANSYS. It is important to accurately simulate the maximum tensile load applicable in order to ensure safety and reliability of the karabiner.

Firstly, I would recommend checking your input keypoints and lines to ensure they accurately represent the dimensions and geometry of the karabiner. Any small discrepancies can greatly affect the simulation results.

In regards to the VDRAG command, make sure you are using the correct units and that the cross-sectional area is defined correctly. You can also try using a different element type, such as SOLID185, to see if that improves the accuracy of the drag.

Another possible issue could be the meshing of the model. Make sure the elements are properly connected and that there are no gaps or overlaps in the mesh. You can also try refining the mesh in areas of high stress concentration to get more accurate results.

If you have tried all of these suggestions and are still facing issues, I would recommend reaching out to ANSYS technical support for further assistance. They have a team of experts who can help troubleshoot and provide guidance on how to accurately model your karabiner.

I wish you the best of luck in your simulation and meeting your deadline. Safety is of utmost importance and it is commendable that you are taking the time to accurately model the karabiner. Keep persevering and seeking help when needed.
