Summary<br />
Proof.<br />
Demonstration of alternative to shear-mode MR damper<br />
Previous considerations<br />
Overparametrized → per<strong>for</strong>m normalization<br />
Ikhouane and Dyke<br />
The fact that lim ρ−→∞ ψ σ,n(¯x tp) = −1 is independent from σ and n <strong>for</strong> large values of ρX max<br />
Proof<br />
Conclusion → <strong>for</strong> large values of ρX max, the values of the parameters σ and n are irrelevant.<br />
After considering the previous alternatives a new model is suggested<br />
F(T) = k vẋ(t) + k vF c(ẋ)<br />
k x and k w are voltage dependent, and F c is the Coulomb dry friction <strong>for</strong>ce representation<br />
F c(ẋ) = 1 <strong>for</strong> ẋ > 0<br />
F c(ẋ) = −1 <strong>for</strong> ẋ < 0<br />
Disadvantage → discontinuity at zero velocity or numerical instability when the ẋ of the damper is<br />
close to 0<br />
