It is not always possible to obtain the characteristics matrices from model parameters obtained by experimental model analysis such as curve fitting. For example, if the degrees of freedom of a mathematical model analysis such as curve fitting. For example, if the degrees of freedom of a mathematical model are different from those of the structure identified, in almost all cases, contradiction occurs between the model parameters when transformed to physical parameters. This paper proposes a method of identifying the physical mass, stiffness and damping matrices from model parameters without contradiction using a nonlinear optimization technique with equality constraints. A new curve fitting method in the frequency domain is also proposed. Some numerical and experimental model are examined to validate this method.
