The critical speed of one turbopump rotor on elastic support was computed by FEMQZ.

计算分析了某涡轮泵转子在弹性支承下的临界转速.

This paper mainly discusses available structures of the liquid hybrid bearings and the key technologies that need to be solved for the liquid rocket engine turbopump .

针对液体火箭发动机涡轮泵特殊工作环境，讨论了流体动静压轴承可采用的结构形式和需要解决的关键技术。

The results show that the turbopump faults can be detected effectively by using the amplitudes of rotor first, second and third order critical frequency as well as axial intrinsic frequency.

结果表明，基于转子的一阶、二阶和三阶临界转速以及轴向固有频率幅值能有效地检测涡轮泵的故障。
