Analyzing on the fault of local rubbing caused by compatible misalignment of rotors, a dynamic model for the rotor system with misalignment and rub-impact was established. Then the dynamic behaviors of this system, which varied with the values of parallel misalignment and declination, were investigated by using numerical integral method.

以水輪發(fā)電機組轉子系統(tǒng)為研究對象，針對剛性聯(lián)軸器綜合不對中引起轉子局部碰摩的問題少妇乱淫特黄A片，建立了機組轉子不對中–碰摩耦合故障的動力學模型和微分方程男人扒女人添高潮视频动态，并利用數(shù)值積分方法研究該系統(tǒng)隨不對中平行量和偏角參數(shù)變化的動力學行為。

By virtue of bifurcation diagrams, Poincaré maps, orbits, time histories and frequency spectrum diagrams, the nonlinear dynamic responses of the generator rotor and hydraulic turbine rotor with coupling faults were analyzed. The results confirmed rich nonlinear motions such as periodic motion and quasi-periods with different values of parallel misalignment and declination. Moreover, the process of rub-impact is so complex that many low frequencies with large amplitude are in the range of

The transformation of the yaw moment under differential brake and the impact of the slip ratio and road surface friction coefficient to the yaw moment were analyzed. The distribution method of the brake force was confirmed. After analyzing the observability of the control system, the state observer was designed, the evaluation of the side slip angle was completed and result of the evaluation wan validated.
