Force analysis in bolt assemblies:
in accordance with VDI 2230, Part 2
Calculate multi-bolt connections according to VDI 2230, Part 2, realistically evaluate loads, and reliably determine the bolt under the highest stress.
That's what this seminar is about
From force analysis, stress analysis, and load distribution to the safe design of multi-bolt fasteners.
Multi-bolt connections according to VDI 2230, Part 2
Calculate and safely design multi-bolt connections in a methodical manner and in accordance with guidelines.
Assessing stressors accurately
Reliably estimate axial, shear, torsional, and bending loads and assess their effect on the bolt field.
Load-optimized positioning of screws
Identify advantageous screw arrangements and deliberately avoid unfavorable placements.
Suitable methods for load determination
Select a calculation method appropriate for the application and reliably assess the quality of the load determination.
