IGBTs damages caused by PMSM demagnetization are analyzed firstly.

The performance of the developed scheme is validated through a set of simulated experiments of PMSM demagnetization. The result shows that accurate estimation of demagnetization condition is obtained, and effective real-time reconfigurable control decisions are achieved which can extend lifecycle of the whole system.","PeriodicalId":281875,"journal":{"name":"2017 Prognostics and System Health Management Conference (PHM-Harbin)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129495135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the existing literature, most RUL prediction methods are under the assumption that there is no maintenance activity during the whole life time of the degrading system. However, most practical systems experience various kinds of maintenance activities when they are in operation. This article presents an approach to predict the RUL of a class of nonlinear degrading systems with stochastic maintenance. To predict the RUL for systems with stochastic maintenance, a wiener process based degradation model is proposed. The switches between states of normal operation and maintenance are described by a continuous time Markov chain (CTMC). In addition, the maximum likelihood estimation (MLE) is adopted to estimate both unknown parameters in the degradation model and the transition probability between normal operation and maintenance. The analytical form of first hitting time (FHT) of degradation process is difficult to derive with the presence of maintenance activities. To avoid complicated mathematical derivation of stochastic differential, Monte Carlo method is used to obtain a numerical result of the RUL distribution. A numerical study is presented to illustrate and validate the proposed method.","PeriodicalId":281875,"journal":{"name":"2017 Prognostics and System Health Management Conference (PHM-Harbin)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129564612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The previous studies about reliability analysis have focused on a single unit or simple system with s-independent failure processes and failure times. The new models are different from previous studies by extending unit-level degradation model to the system level. In this paper, each component in the system can be invalid owing to a hard failure process or a soft failure process. These failure processes mentioned-above are not only competing but also dependent and whichever happens first, the component fails. Moreover, the hard failure threshold can change due to the increment of the total degradation. Then, the reliability models for series, parallel, series-parallel system were derived respectively. Finally, numerical examples about Micro-electro-mechanical System (MEMS) are illustrated to verify the developed models and the results are effective. These models could be applied in MEMS or used in many other similar systems.","PeriodicalId":281875,"journal":{"name":"2017 Prognostics and System Health Management Conference (PHM-Harbin)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121503159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In fact, blade crack is one of the costliest sources of damage in gas turbine. Detection of cracks of blades is important to ensure safe and reliable operation of gas turbine engine. A vibration-based damage-detection methodology is presented in this paper to monitor the health condition of gas turbine rotor blade. In order to simulation the real-time dynamic crack propagation of rotor blades, model analysis was performed using a finite element model to calculate the natural frequencies and mode shapes of gas turbine blade, the possible crack initiation location was determined, the natural frequencies and mode shapes changed as the crack growing, indicating the feasibility of the methodology to capture the dynamic health condition of blade on-line. Simulation results have indicated the capability of the methodology in evaluating the changes of blade vibration signals once damage is initiated of growing, and in consistently detecting cracks of damaged blade to monitor the health condition. Additionally, the results indicated that blade natural frequency decays slightly when crack propagating, providing the potential for reliable diagnosis of the gas turbine blades with crack fault, thus the implementation of blade health monitoring system will be the approach to achieve condition-based maintenance.","PeriodicalId":281875,"journal":{"name":"2017 Prognostics and System Health Management Conference (PHM-Harbin)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114981567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnosis aims to monitor the fault state in real-time while prognosis predicts the evolution of fault state and remaining useful life (RUL). Traditional Riemann sampling-based FDP (RS-FDP) takes samples and executes algorithms periodically and, in most cases, requires significant computational resources, which makes it difficult to be implemented on hardware with very limited computational capabilities. To overcome this bottleneck, a Lebesgue sampling-based FDP (LS-FDP), in which FDP algorithms are implemented “as-needed”. In LS-FDP, a set of Lebesgue states are defined on the state axis. The computation of LS-based diagnosis is triggered only when the value of measurements changes from one Lebesgue state to another, or “event-triggered#x201D;. This method significantly reduces the computation demands by eliminating unnecessary computation. This LS-FDP design is generic and able to accommodate different FDP algorithms. In this presentation, the design of LS-FDP and its application to engineering systems will be discussed in details. The efficiency of LS-FDP is verified by comparison with those of its RS-FDP counterparts.","PeriodicalId":281875,"journal":{"name":"2017 Prognostics and System Health Management Conference (PHM-Harbin)","volume":"2018 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128046871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper introduces the system structure and function realization of the prognostics and health management platform for high-speed railway traction power supply equipment. The core part of the platform is the PHM software, it can show the equipment monitoring and detection information on the interface. Besides, by combining the algorithms for fault prediction, fault diagnosis, health assessment, reliability assessment, risk assessment and maintenance strategy decision-making, it can also show the results calculated according to the PHM algorithms.
