    In this study, combined with XXX XXX, reverse multiple degrees of freedom vibration problem solving, to give non-linear force vibration system, reverse forecast multiple unknown springs, damping, and sensitivity to do amendments for XXX to XXX to improve the convergence of the iterative program Speed.

    The results show that the methods for solving the three cases, the simulated measurement error is less than 5% of cases, able to effectively reverse the unknown predicted multiple springs, damping, and the percentage error is smaller than the program operation 4.5%.
