As the important component of the helicopter equipment,vibration active control system has the effect of effectively reducing the vibration level of the helicopter,its safety level directly determines the damping ability of the helicopter.In this paper,a helicopter vibration active control system is taken as an example,through the functional hazard analysis,the fault state list of all function is made.Taking the catastrophic and dangerous fault state as the top event,the fault tree analysis is carried out,and its probability is calculated to evaluate whether the safety of the vibration active control system meets the requirements.
