Different calculations can be executed for the shaft/hub connections (feather key, interference fit, polygon, etc.). The shaft/hub connections include feather key, cylindrical or conical interference fit, spline connection, splined shafts, Woodruff keys, and polygons. Likewise it is possible to calculate different threaded joints with consideration of nuts and washers on the basis of VDI 2230. Welded connections with different seams, adhesive and solder connections can be calculated. Bolts and pin connections are organized in four calculation types and can be calculated in accordance with these calculation types.
