I am currently trying to analyze a part that will have 4 screws and 2 shear pins connecting it to another part of an assembly. The assembly I am trying to analyze is shown in the pictures.
The problem that I am having is that I do not know for sure which items or surfaces to fix. I want to not only analyze the main part, but I also want to analyze the 4 screws and shear pins with it.
The analysis that I am showing in the pictures below was completed by fixing the surface tips of the 4 screws and 2 shear pins protruding through the part. This causes the screws and shear pins to act as if they were beams which is not correct, hence the high concentrations of stress on the screws and shear pins.
How do I correctly anlalyze this part INCLUDING the screws and pins?
Thanks in advance,
Kyle
Hi Kyle; It appears you've done it using actual solid models of the fasteners and contact sets. Alternatively you could use "Bolt Connectors". They are virtual fasteners and will report the shear, axial loads and bending moments on the fasteners in a table. They are located in the Simulation Tree under folder item "Connections/Bolt" - for specifying bolts between components, and folder item "Fixtures/Foundation Bolts" to fasten the bolts to a ground plane. Hope that helps. -Tony
