英文摘要：

A new electro-hydraulic exciter that consists of rotary valve and micro-displacement double-functioned hydraulic cylinder was proposed to realize different kinds of waveforms. Calculated fluid dynamics （CFD） simulation of rotary valve orifice reveals that orifice exists the two-throttle phenomenon. According to the finding, the revised flow area model was established. Vibration waveforms analysis was carried out by means of mathematic model and the related experiments were validated. Furthermore, as a new analysis indicator, saturation percentage was introduced first. The experimental results indicate that the revised flow area model is more accurate compared to the original one, and vibration waveforms can be optimized through suitable spool parameters and the revised cylinder structure.
