摘　　要：振动主动控制系统作为直升机的重要组成设备,具有有效降低机上振动水平的作用,其安全性水平直接决定直升机的减振能力。本文以直升机振动主动控制系统为例,通过分析其功能危险因素,形成所有功能的故障状态清单。以灾难的、危险的故障状态作为顶事件进行故障树分析,并计算其发生概率,以评估振动主动控制系统安全性是否满足要求。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.
