振动台垂臂安装条件下与离心机机臂的相互影响的计算

分析了振动台垂臂安装情况下振动离心复合系统的受力，建立了相应的物理和数学模型，计算出振动台和离心机的相互影响。计算结果表明：振动台的振动引起离心机机臂的上下摆振，在共振频率段影响很大，离心机机臂的上下摆振在远离共振频率段对振动台几乎没有影响，在共振频率段有一定影响。

Calculation of the Interaction between the Vibration Table and the Arm of Centrifuge under the Conditions of a Vibration Table Fixed in Vertical Direction of the Centrifuge

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.
