In this paper, a force acting on the moving section of vibration table and the arm of centrifuge is analyzed as the vibration table is fixed in a vertical direction of the centrifuge. And corresponding physical and mathematical models are established. The interaction between the vibration table and the centrifuge is calculated. The calculated results show that vibration of the vibration table causes the vibration of the arm of centrifuge in vertical direction and a very strong vibration of the arm of centrifuge appears in resonant frequency section, and that vibration of the arm of centrifuge in vertical direction almost has no influence on the vibration of the vibration table in the section far from the resonant frequency section but has an influence to some extent in the resonant frequency section.
