摘　　要：结构健康监测系统能够连续收集结构信息,有助于工程师采取适当的维修决策,确保结构安全,减少失效的风险成本。但结构健康监测系统在国内直升机方面的应用仍处于初步阶段,原因之一是监测信息和结构状态存在不确定性,导致其经济效益在投入前难以衡量,并且该系统非常昂贵,使得很难确定收集这些信息是否值得,从而阻碍了其使用和发展。因此,定量化不确定性下结构健康监测系统的潜在效益,对推动该技术的在国内直升机上的应用和发展具有重要意义。本文针对直升机可修件提出了一种基于贝叶斯决策的监测信息价值量化方法,利用振动信息与贝叶斯理论对结构状态进行概率化表征与更新,建立了不确定性下状态概率模型、损伤成本函数和监测不确定模型及其基础数据获取方法,实现了监测系统经济性量化。以贝尔427桨叶为例,对基于振动的直升机监测系统的经济性进行了量化。The structural health monitoring system can continuously collect structural information,which helps engineers make appropriate maintenance decisions to ensure structural safety and reduce the risk cost of failure.However,its application in domestic helicopters is still in the preliminary stage.One of the reasons is that there is uncertainty in monitoring information and structural state,which makes it difficult to measure the economic benefits before put into use.Moreover,the system is very expensive,which makes it difficult to determine whether it's worth collecting structural information,thus hindering the application and development of structural health monitoring systems.Therefore,quantifying the economic potential benefits of structural health monitoring under uncertainty is significant to promote the application and development of this technology in domestic helicopters.A method aimed at helicopter repairable parts maintenance was proposed to quantify the value of monitoring information based on Bayesian decision.Vibration monitoring information and Bayesian theory were used to probabilistically characterize and update the structural state,the state probability model,damage cost function.The monitoring uncertainty model were established under uncertainty,implementing its economic quantification.Finally,taking Bell 427 blade maintenance as an example,it quantified the information value of the helicopter blade health monitoring system based on vibration.
