The mechanical charateristics of the electro-hydraulic servo system in the centrifuge fieldare analyzed. The hydraulic pressure law in the centrifuge field indicates the existence of the centrifugehydraulic pressure. The mechanical characteristics of the slide-valve and the dual nozzle flapper valveare studied, and it is found that the centrifuge field can not only increase the driving force or momentof the function units, but also decrease the stability of the components. Finally by applying Gaussminimum constraint principle, the dynamic model of the electro-hydraulic vibrator in the centrifugefield is established, and the mechanical restriction of the system is also presented. The study will behelpful for the realization of the combined vibration and centrifuge test system.
