Research on MRD Parametric Model Based on Magic Formula

Table 1

Parameters’ definition and the range of their values.

A	The hysteresis factor, determines the half width of MRD hysteresis, generally positive
B	The stiffness factor, generally positive
C	The shape factor, determines the “S” curve shape and change around 1
D	The peak factor, determines the MRD damping force saturation, generally positive
E	The curvature factor, determines the yield characteristics, the general value is less than 1
kc	The viscous damping coefficient
k	MRD stiffness coefficient
f0	The bias force
