摘　　要：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。In the paper, a mathematical model of electrodynamic vibrator on centrifuge under the compund vibration environment is founded by the method of multirigid body analysis and the theoretical solution is derived, with the aid of the model, an all round emulational analysis is conducted. The emulational results justify the theoretical solution, and the modelling creates a foundation for designing of the control system.
