针对航空航天领域可能存在的实际复杂环境 ,分析了振动台沿离心机切线方向安装情况下振动离心系统复合台的受力及稳定性 ,并作了相应的建模和仿真。理论分析和仿真结果表明 :振动台沿离心机切线方向安装的复合台所模拟的对象为有径向科里奥利力存在的变过载与振动的复合 ;离心振动系统复合台的不稳定性主要由共振引起 ,在低频段影响很大 ,但未出现比垂臂安装超常的不稳定
In view of the actual complex environment that may exist in the field of aerospace, the force and stability of the compound platform of the vibration centrifugal system under the condition of the tangential direction of the centrifuge are analyzed, and the corresponding modeling and simulation are made. The theoretical analysis and simulation results show that the object simulated by the compound table installed along the tangential direction of the centrifuge is a combination of variable overload and vibration with radial Coriolis force. The instability of the composite table of the centrifugal vibration system mainly consists of Resonance caused a great impact in the low frequency band, but did not appear than the vertical arm installation extraordinary instability
