SiC ceramic has been extensively applied in precision bearings, sealing element, steam-turbine rotor, burner nozzle, heat interchanger parts, atomic reactor materials and etc. because of its excellent properties in high temperature mechanical properties, antioxidatio, abrasion resistance, thermal stability, smaller coefficient of thermal expansion, larger thermal conductivity, hardness, thermal shock and chemical corrosion.

SiC陶瓷具有优良的高温力学性能，抗氧化性强、耐磨损性好、热稳定性佳、热膨胀系数小、热导率大、硬度高以及抗热震和耐化学腐蚀等优良性能，被广泛应用于精密轴承、密封件、气轮机转子、燃烧喷嘴、热交换器部件及原子热反应堆材料等，并日益受到人们的重视，应用前景十分广阔。

The 3-dimension solid model of the 8th turbine rotor blade of some type aero engine is constructed in software UG, and the numerical calculation region of stream field in ECM is set up in special flow field calculation software FLUENT based on the principle of hydrodynamics. The distribution of 6-dimension forces is got after numerical calculation, and the equation between 6-dimision forces and interelectrode gap is set up.

基于流体力学原理，用UG造型出某型航空发动机8级涡轮转子叶片，用流场计算软件FLUENT构造电解加工中叶片的流场计算区域，经数值计算得到六维力的分布，并从理论上建立六维力与间隙之间的关系方程式，为后续试验研究提供了参考依据。

The added damping by the interstage seals also permits operation at the second critical speed without significant rotor vibration.

加上阻尼由中间的封条还允许操作在第二次临界转速无显着转子振动。

Added support stiffness provided by the pump interstage seals raise the rotor first critical speed to greater than one-half the maximum operating speed which prevents subsynchronous whirl.

补充，支持刚度所提供的泵中间的封条，提高转子的第一临界转速为大于1的一半，最高运行速度以防止subsynchronous旋转。

An important candidate measure is to balance its rotor with high precision. The traditional dynamic balancing techniques are based on linear time invariant theory.

经典动平衡方法是基于线性时不变理论提出的，而实际转子系统都在一定程度上存在着非线性和时变性等不确定性因素。

The rotor now is attracted to the iron core - and at this point we get useful work.

转子，现在是吸引铁心-在这一点上我们得到有益的工作。

It is applied only when the rotor approaches the sticking point where it is lined up with the iron core.

它仅适用于当转子方式的症结在那里，它是左列同铁芯。

Furthermore a general method is proposed to treat the contact boundary between the rotor bar and iron core.
