I was wondering if someone can advise on what are the best restraints to model the wrench-bolt system please (Check picture). I have calculated the contact forces acting on the wrench between the jaws, but I am having trouble figuring out how to restrain the model to get the best results.
Do the study with both the bolt and the wrench, fix the threaded area of the bolt and apply the load to the end of the wrench. Apply a "no penetration contact" to all the contacting faces between the wrench and the bolt. then you will probably need to apply a roller slider to the face of the wrench to keep it from moving. if you get a "large displacement" error rerun with "soft springs" turned on to see what is moving
