In the bolt calculation according to VDI 2230 (module SPK), additional strength classes for nuts have been implemented in KISSsoft. Also new is the feature that stress can now be calculated either with a reduced torsional stress level or with none at all.

Furthermore, CADFEM, together with KISSsoft in ANSYS, have developted the "WB/Bolt Assessment under VDI2230" tool for automated evaluation of bolts so complex component part geometries can be calculated efficiently. The benefit of this tool is the fast and reliable assessment of large housing structures with many bolts. Consequently, the user is freed from tedious, repetitive tasks and can concentrate on the development of optimal and reliable gear boxes.
