摘　　要：以电站汽轮机为例 ,研究探讨了设备的功能可靠性仿真方法 ,根据该设备的性能退化规律 ,建立了其性能退化模型 ,开发了功能可靠性仿真算法 ,并对其进行了功能可靠性仿真。计算得到的设备可靠性数据符合同类设备的规律 ,算法可用于同类设备及复杂热力系统的功能可靠性仿真计算。A new method and algorithm of functional reliability simulation for steam turbine is proposed and the degeneration model is established based on the degeneration laws of the steam turbine. By taking power station steam turbine as an example, the turbine′s functional reliability is simulated. The functional reliability simulation result indicates that the reliability data of the power station steam turbine is consistent with that of the practice equipment. The simulation results are feasible and the simulation algorithm is applicable to functional reliability simulation of the similar equipment and complex thermodynamic systems.
