J】 four,Christian Louboutin, count down to validate the theory and method, as shown in Figure l Two dual-rotor system is optimized bearing damping. Figure l Ⅱ for the rotor model,ed hardy bikinit, Figure l6 is segmented constraint subsystem. K1-2840N/cmK2-5129N/cmm1 = 5.7kgJ1 = 244.5kg-cm2 = 7.03kgJ2 = 366.13kg-cm (b) rotor model and 1 double scoop bound eccentric rotating disk subsystems moment the two were 0 .001 mm and 0. oIf1m. According to the model of the situation,Abercrombie France, take 0 ≤ c1 ≤ 330 (N · S / cm), O <Cz <330 (N · S / era) 0 ≤ maxXi ≤ 0.01 (Ci] 1), 1 ≤ maxki ≤ 2 so to optimize the mathematical model rMi wrapped in a tough position and end optimization (29) (30) bearing damping (N · S / era) cIc initial 1] .0 I1.0 balanced response to the maximum (cm) 2 bearing rotor rotor 1I maximum dynamic load factor final objective function value of 9.7d} 18.38c0 · 004l0 · 003 iv giant of a first order plant. eleven Vibration Engineering Figures 2 and 3 were first-order loop response of flexible lines and the second initial and final value of the elastic response The initial and final value of the line. 2 of a step response of the Elastic Line Magic before jumping 3, Volume 3, elastic cord second-order response to V. CONCLUSIONS 1. for supporting dynamic sensitivity analysis and parameter optimization parameters such as modulation operation, the proposed mode synthesis method is quite effective. 2. there is an optimal value of the bearing damping. by supporting optimal damping, the system can greatly reduce dynamic load imbalance in the level of response and support.
