Fastener Functionality in SimSolid - Computer Aided Technology
Summary
SimSolid by Altair is comprehensive, fast, accurate and easy-to-use software that can perform advanced structural analyses on complex, fully featured CAD assemblies within minutes. As part of the preprocessing phase, most other FEA programs require simplification of the CAD model before the study can be solved. SimSolid will also apply a sliding connection (depicted by yellow crosshairs in the image below) between the shank of the bolt and the internal cylindrical face of the holes. After clicking the “OK” button, the graphics window displays a counterclockwise rotation arrow around each nut that has been tightened. We can check that our pretension has been applied correctly by comparing the input pretension value with the value of “Axial force at head.” While post processing stress results in our model, if we click on the magnifying glass button in the lower left corner, the result window will zoom to an isolated close-up view of the selected bolt, where we can get an accurate depiction of local bolt stresses.
