一、POGO振动的不稳定现象及其预防措施阿波罗的POGO振动的遥测表明:POGO振动的不稳定现象是实际存在的。不仅土星Ⅵ级存在,而且土星Ⅶ级也存在。正如一系列文献所论述的,POGO振动是一个闭回路的自激振动,它属系统动力学问题,是个潜在的有害的工程问题。若POGO振动严重了,它会导致飞行器失败,如欧洲早期的钻 First, the POGO vibration instability and preventive measures Apollo POGO vibration telemetry shows: POGO vibration instability is actually there. Saturn Ⅵ level exists, but Saturn Ⅶ level also exists. As discussed in a series of literature, POGO vibration is a self-excited vibration of a closed circuit that is a systematic kinetic problem and is a potentially detrimental engineering problem. If the POGO is seriously vibrated, it can cause the aircraft to fail, as in early European drilling
