A system program of curve-fitting for general purpose is made to analysis the modal parameters from a transfer function obtained by a vibration test and to reconstruct the frequency curve of the transfer function. Both the frequency domain and the time domain curve-fitting is possible under assumption of three kinds of dampings, namely the proportional viscous, general viscous and the hysteretic dampings. A transfer function of a mass-spring system of three degrees of freedom is fitted by six methods with this program, and calculated results of modal parameters are compared with the rigorous solution. Next, a transfer function of a steel plate obtained by the vibration test is fitted with this program, and the result is compared with the experimental one.
