本文用多刚体分析的方法建立了在复合振动环境试验中离心机上电动振动台的数学模型，推导出了理论解，并对其进行了全面的仿真分析，仿真结果验证了理论解的正确性，从而为控制系统的设计提供了依据
In this paper, the multi-rigid body analysis method was used to establish the mathematical model of the electrodynamic vibration table on the centrifuge in the composite vibration environment test. The theoretical solution was deduced and a comprehensive simulation analysis was carried out. The simulation results verify the correctness of the theoretical solution, Thus provides the basis for the control system design
