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%.

This research and application of XXX with XXX, reverse equations with multiple degrees of freedom vibration problems, nonlinear vibration systems outside, spring and damping coefficients of the reverse forecast multiple sets of unknown, and sensitivity correction of XXX, XXX improving program speed of convergence of iterative.Study results showed that research methods in solving the three case studies, simulation cases of the measuring error is less than 5%, which can effectively reverse forecast spring and damping coefficients of multiple sets of unknown, and the program operator error percentage is less than 4.5%.
