Weights of 4, 3, 2, and 1 were assigned to the bulk density, hysteresis loss
, hardness, and tensile strength correspondingly, as ranked by their importance.
While there has been a significant amount of study on eddy current losses in magnets of PM synchronous machines, an in-depth study on hysteresis loss
is not available.
Higher values of tan ([delta]) show higher hysteresis loss
in UDPCs compared to FGPCs having any ascending/descending stacking sequence.
Apart from the magnitude, this is the reason why [P.sub.H] = 0.4 MW/kg was experimentally observed for the cobalt ferrite nanoparticles, despite the conventional prediction of no hysteresis loss
under the experimental conditions.
Interestingly, tension set and hysteresis loss
of FVP-filled and unfilled fluororubber vulcanizates do not change appreciably on incorporation of FVP.
was determined up to the second cycle by stretching dumb-bell test pieces to a strain level of 100% in the Zwick UTM.
Key statement: A rubber composition for a tire tread including 100 parts by weight of a diene-based rubber and 5 to 150 parts by weight of carbon black having a nitrogen adsorption specific area N2SA ([m.sup.2]/g) of 80 to 150 and satisfying a relationship between a TINT (%) and dibutyl phthalate absorption DBPA (ml/100 g) of TINT (%)>1.4 DBPA (ml/100 g) and capable of increasing the frictional force without impairing the hysteresis loss
The hysteresis loss
was calculated by the ratio of the area of the loop between the loading and unloading curves to the area under the stress-strain curve used.
Key statement: A rubber composition for an inner liner improving air retention property of a tire, lowering hysteresis loss
and further preventing crack growth is provided.
at 100% elongation was measured at 25[degrees]C by subtracting the area under the force-retraction curve from the area under the force-deformation curve (up to 100% elongation).
Together with the high coupling efficiency of VP Si 363, this strongly reduced silica network leads to a very low hysteresis loss
of the compound.
As the applied field is increased and approaches the value of the coercive field polarization reversal occurs giving rise to a large dielectric nonlinearity and hysteresis loss
. At large fields the value of the spontaneous polarization tends to saturate.
