The parameter identification of a new hysteretic nonlinear metal rubber damper system is studied in this paper. Firstly, the advantage of the new metal rubber damper which composed by two components is proved by the static and dynamic test comparing to the damper included only one metal rubber. Secondly, the constitutive of bilinear hysteresis model and parameter identification equation are obtained. Then the parameter of the new damper system is identified by generalized least squares estimation. In the last, the simulation result is compared with the real values, it shows that the method is simple, effective, high precision, and it is also reliable and applicable to the corresponding engineering.
