BasicDynamicLoadRatingCalculation
The method for estimating the basic dynamic load rating in ISO/TR 1281-1:2008(E) may be different than that in ISO 281:2007 for ball bearings, since the ISO/TR 1281-1:2008(E) method uses the groove diameters of the races. Roller bearings have the same estimated basic dynamic load rating whether you use the method in ISO 281:2007 or ISO/TR 1281-1:2008(E).
Declaration
public EnumWithSelectedValue<BasicDynamicLoadRatingCalculationMethod> BasicDynamicLoadRatingCalculation { get; set; }
Property Value
BasicDynamicLoadRatingDividedByCorrectionFactors
The basic dynamic load rating 'Cr' defined in ISO 281:2007 includes a reduction factor λ to account for stress concentration and a factor ν to account for a single exponent used in the life formula. In ISO/TS 16281:2008 the detailed stress distribution is calculated for the bearing elements, so these factors are not required. In equations 47, 48, 50 and 51 of ISO/TS 16281:2008 the basic dynamic load is divided by the 2 factors to cancel them out of the basic dynamic load rating. If you have specified basic dynamic load ratings for bearings that do not include the 2 factors then this option can be used to not cancel them in the ISO/TS 16281:2008 calculations.
