The deep vibrator is an important equipment of foundation improvement. It works through eccentric masses with high-speed. But the traditional eccentric structure will stir the oil around it, and it will result in the loss of motor power. The paper analyzed the stirring phenomenon, and got the level and specific data of stirring and swirling through fluent software. After principle analysis, a new type of anti-churning eccentric structure was put forward, which can effectively avoid stirring phenomenon. Otherwise, the new structure will also not produce irregular vibration because of swirling, then it can work with a better performance. In addition, the contrast of dynamic performance between a traditional and new structure was carried out in the paper and proved that the new structure has a better working performance. Modeling data in the paper is from surveying and mapping, so the conclusion can be taken as guidance for vibrator designing.
Key words:    vibrator    eccentric weight    oil stirring    fluent    dynamic properties
