In general, the different DOF in CViS are coupled, which will widen the resonant frequency band and increase the possibility of resonance. Therefore, by increasing EDR of different DOF in CViS, the vibration and noise levels can be effectively improved. The current decoupling methods include elastic center method, stiffness matrix method and energy decoupling method [16]. Compared with the former two methods, the energy decoupling method is not limited by the structure scale, installation position and angle of the system, so this paper chooses the energy decoupling method to study.<br>
