摘要：

The AMB's impact properties are studied in this paper based on AMB in the helium circulator for the 10 MW high temperature gas cooled reactor (HTR-10). The impact force when the vertical rotor drops is calculated, and the amount of deformation of the auxiliary bearings is calculated based on the quasi static analysis. The calculation results show that the acting force between the rotor and the auxiliary bearing is roughly the same, no matter what is the rotational speed of the rotor. And after a certain time, the acting force reaches a constant value which is only concerned with the rotor (the rotor speed, quality, and etc). The deformation amount of the auxiliary bearing is also roughly the same according to the results. The deformation amount appears as the bearing's vibration displacement on the macro level. So it can measure the state of the auxiliary bearing. © 2016, Yuan Zi Neng Chuban She. All right reserved.
