In some systems, like resonators, the aim is to get as much amplification as possible. This leads to another popular damping measure: thequality factororQ factor. It is defined as the amplification at resonance. The Q factor is related to the damping ratio by Another starting point for the ...
1) damping ratio influence factor Rξ 阻尼比影响系数Rξ1. The results demonstrate that the effect of damping ratio on strength-reduction factor is obvious,the period greatly influences the damping ratio influence factor Rξ,whereas the effect of ductility and soi. 其中周期对阻尼比影响系数Rξ的...
Modification Factor (R) and Displacement Amplification Factor (C_d) was calculated on the basis of the damping ration being 0.05, for other instance, that is, the damping ration was not 0.05, a damp-modifying factor R_味 was introduced to account for the influence of different damping ratio...
The ratio wk(G)/sk(G) can then be seen as a measure of the inevitable price of obliviousness to the user's model: the smaller it is, the more well-orderable G is. In the ideal case, sk(G)=k=wk(G), all users have exactly the same preferences and every damping variable yields ...
“effective values” which are model dependent in the sense that they incorporate all the approximations made in the model. For example, we neglect the second-order uniaxial anisotropy, the even components of chiral damping21as well as the corrections to the gyromagnetic ratio19,22, we use an ...
After the cursor is on the peak value, right click on the cursor and select “Calculations -> Q” or “Calculations -> Damping Ratio” as desired as shown inFigure 10. Figure 10: Right click on the cursor and select “Calculations -> Q” or “Calculations -> Damping Ratio" ...
Meanwhile, the loss factor is the ratio of the loss modulus to the storage modulus. Therefore, when the graphene content is less than or equal to 0.5%, the loss factor increases significantly, and the damping properties are significantly enhanced. However, when the content of graphene reaches ...
(3)films was determined by means of SQUID magnetometry and plotted in Fig.2. A linear decrease inMsis observed with an increasing ratio of Py to Fe. One can calculate the expected trend ofMsas a function of Py to Fe ratio by weighting the individual magnetizations by the corresponding ...
79. The variation of the magnetostriction constant from − 0.7 × 10–5to 1.5 × 10–5was caused by changing of a Ni-to-Fe ratio where λ = 0 for Ni80Fe20composition. Nevertheless, it is difficult to find formulas which correlate the magnetoelastic constants and damping ...
from the FMR measurement f = γ 2π H r H r + 4π Ms− 2K Ms 1 2 (1) where γ is the gyromagnetic ratio (=1.856 × 1011 Hz/T) when the spectroscopic splitting factor g is taken as 2.1....
