According to the continuity of frequency response function curve, dichotomy of resonance and non-resonant zone in conventional frequency reliability analysis is debatable. New method of multi-state frequency reliability analysis with multiple failure modes is proposed, in which, randomness of structural parameters and excitation frequency are considered. Monte Carlo simulation is applied to estimate the system frequency availability, simultaneously, accordance with correlation analysis, influences of each structural random parameters are identified. The new method is applied in the servo turret system, whose dynamic model is established by transfer matrix method of multibody system. Then, its frequency availability and the most related structural parameter are obtained, which provides the basis for further optimization.
