This paper deduced the stability condition of POGO vibration system using Routh criterion based on the dynamic model of POGO vibration system in liquid rockets. Aimed at the uncertainty of stability parameters of POGO vibration system in liquid rockets caused by the uncertainty of the system itself and all kinds of environment, it is used Monte Carlo method to make the simulate target practice analysis on the stability of POGO vibration system in liquid rockets. The results show that the stable frequency of POGO vibration system in liquid rockets has the tendency that first increasing and then decreasing as targeting times increases, but the change is very small. It provides a theory reference for POGO vibration abatement in liquid rockets.
