The purpose of this research is to find the right fault search strategy for these hydraulic actuators. According to the characteristics of hydraulic systems, this study proposes a fault search strategy analysis method based on fuzzy fault tree theory. Considering the maintenance factors of hydraulic actuators, such as the searching cost, the failure probability and the degree of influence, the optimal search strategy model for fault diagnosing of hydraulic actuators is established. The multi objective optimization decision theory and sequential decision theory are also applied in this model. Finally, the fault search order for FAST hydraulic actuators is calculated. The top three fault search components are motor, controller and hydraulic control check valve. The calculated results are in agreement with the reliability test results and Failure Mode Effects and Criticality Analysis (FMECA) of hydraulic actuators. This study has guiding significance for the maintenance of the hydraulic actuators for FAST.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121346717","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}

Robust partitioning is adopted by new architecture to cope with the failure propagation due to resource sharing. However, if the activity of allocating applications to partitions doesn't consider the common cause failure and coupling relations among avionic functions, it can intensify the failure propagation. At present, a lot of researches take into account the application software's functionality and criticality in the software configuration activities, but not include other factors which are also indispensable. In this paper, we proposed a partitioning method from the safety perspective. Firstly, we identified the process of allocating applications to partitions from the partitioning configuration activities referred to Do-297 and built the partitioned system model. Three safety factors which should be satisfied by the process were introduced. Then, we presented the safety constraints based on the safety factors. Finally, we proposed the partitioning strategy on the basic of safety constraints and partitioned system model. This partitioning strategy will be the theoretical basis for the scientific partitioning method in future and ensure the implementation of robust partitioning in Integrated Modular Avionics.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126674736","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}

Correlations of system states contribute to the fault propagation in IMA systems. In other words, when a shared resource goes into an error state, components which have access to that resource may work in a failed state. Additionally, this process is dynamic during the system running. Model-based method is an adequate approach to analyzing system safety dynamically with correlations of system states. Architecture Analysis and Design Language (AADL) has advantage to model for embedded systems. However, it is quite limited to employ AADL dynamically for analyzing system safety. This paper seeks to translate the AADL models into improved colored GSPN models, which have advantage to simulate with system run-time properties such as time and event occurrence probabilities as well as other properties of system components. Furthermore, the paper focuses on this transformation process without any loss of key modeling elements including those properties mentioned above. Based on this work, subsequent analysis can be conducted. A case study is provided for indicating the application of these transformation rules.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"42 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131274585","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}

For the existing problem of storage reliability assessment for small samples of aerospace relays and other electromechanical products produced on a small scale, a particle filter and Bayesian theory based storage reliability evaluation method is proposed. Firstly, with the application of a particle filter, the distribution of the degradation model parameters is estimated by combining the initial distribution of degradation parameters with actual degradation data to predict the distribution of the degradation data for each test time. Secondly, we consider the predicted distribution to be prior information, then calculate the prior estimation of degradation data distribution hyper-parameters within the constraints of reliability distribution function information entropy maximization. Then we fuse the tested degradation data from the samples with the Bayesian formula to compute the posterior estimation of the hyper-parameters. After that, we obtain the interval estimation of storage reliability by solving a non-central t distribution. Finally, a specific aerospace electromagnetic relay was taken as an example to illustrate the method in detail and verify the effectiveness of the proposed method.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130627269","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}
