This balata lies between shake mat is phyletic and various, norms is all ready, facilitate cut into parts cut, assemble agile, can fight effectively press damping, apply to punching machine, forging press, fan, water pump, dynamo, air conditioning to wait for those who shake big Electromechanical equipment damping to use.

该橡胶隔振垫类别众多，标准完备，方便裁切，组装灵便，可有用抗压减振，适用在冲床、锻压机、风机、水泵、发电机、空调等撼动大的机械电子配置减振之用。

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

通过分岔图、Poincaré截面图、轴心轨迹图、时域波形图和幅值谱图系统地分析了发电机转子与水轮机转子在耦合故障下非线性动力学响应，发现机组转子系统随不对中平行量和偏角变化存在周期运动和复杂的拟周期，其碰摩过程非常复杂，机组故障特征频率除主要在1倍频外，还在0.3~0.4倍频处存在幅值较大的谐波分量。

The fault phase and the ground fault generator with the current difference larger than its threshold are thus detected,and the selectivity protection scheme is also presented.
