Abstract: The idea of finite segment modeling with Gauss minimum constraint theory is applied, a nonlinear mathematical model is founded with the method of multi-flexible body analysis, which studies the movement coupling of centrifugal arm and vibrator environment testing in centrifuge-vibration compound, some useful conclusions are obtained by numerical simulation, and theoretical foundation is provided for the design of vibration absorber and system control in compound environment.

Key words: Compound environment, Coupling, Finite segment, Mathematical model, Multi-flexible body
