Table 1

Parameters’ definition and the range of their values.

AThe hysteresis factor, determines the half width of MRD hysteresis, generally positive
BThe stiffness factor, generally positive
CThe shape factor, determines the “S” curve shape and change around 1
DThe peak factor, determines the MRD damping force saturation, generally positive
EThe curvature factor, determines the yield characteristics, the general value is less than 1
kcThe viscous damping coefficient
kMRD stiffness coefficient
f0The bias force
