It refers to the reasonable arrangement of each piece of equipment and component in a limited space. Currently, aircraft equipment cabin maintenance difficulties are common, time-consuming, uneconomical, and are serious maintenance problems. In order to improve the accuracy and quality of maintenance design, a virtual maintainability design method is proposed, using DELMIA as a tool to build the virtual environment, which can be used to verify and improve maintainability. The maintenance visibility, accessibility, operating space, and working gesture are treated as objective functions. The functional constraints and aircraft equipment cabin layout rules are also considered, and are formulated as constraints. Thus, a combination algorithm model for maintainability is presented. According to the characteristics of the equipment layout problem, a modified particle swarm is used to improve the computational efficiency and solution accuracy. Finally, the application of a fighter electronic cabin is studied in detail to illustrate the effectiveness and usefulness of the proposed method. The results show that virtual maintainability design can be implemented to solve the layout optimization problem.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"102 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":"127128550","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}

It is also the newest development in the current equipment system, BIT (Built-In Test), because of its condition monitoring abilities. PHM technology marks a transformation from condition monitoring to health management. The PHM design philosophy has also been adopted in the development of new generation military and civilian equipment. In the complex systems of military and civilian equipment, such as electromechanical systems and flight control systems, the PHM design has been adopted as a new function design. The diagnostic capabilities of PHM are its core foundation, and its design level has a direct influence on the overall efficiency of PHM. This influence is mainly reflected in its fault detection capabilities, and its comprehensive processing and analysis capabilities. In order to validate the PHM fault diagnostic design level, we propose a new diagnostic capability validation method for complex systems. Our proposed method is based on testability validation technology, and provides a guideline for technological approaches for PHM diagnostic validation that evaluates the integrity, rationality, and effectiveness of PHM diagnostic capabilities. Moreover, our proposed method can expose design defects and weak links, allowing for an iterative optimal design.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"26 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":"127248562","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}

Uncertainty analysis is a core problem in PRA, which must be addressed. There are several methods for analyzing uncertainty such as Monte Carlo simulation, interval analysis, probability bounds, the Dempster-Shafer theory of evidence, and fuzzy set theory. When the probability distributions of random input variables are specified, but the parameters are intervals, probability bounds analysis is an effective way to analyze the uncertainty of PRA. By constructing the probability boxes (p-boxes) of basic events, using the event chain model of PRA, uncertainty can be propagated from basic events to end states. The uncertainty analysis results verify the feasibility of probability bounds analysis of PRA in high microgravity science experiment system, and will provide a reference for the subsequent study of the quantitative risk assessment of space utilization payloads.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"3 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":"133035646","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 traditional performance and reliability analysis, the performance and reliability are generally analyzed separately. However, when one of these cannot meet the requirements, researchers usually have to redesign the system. In order to solve these problems, the optimization of both the performance and reliability of a BLDC motor was proposed. This paper shows how the control system model of a BLDC motor was simulated using Saber, which was modified by the engineering data. A sensitivity analysis was used to determine the design dependent parameters and performance parameters of a BLDC motor, which could vary as a result of the manufacturing conditions, environmental temperature, and device degradation. The performance of a BLDC motor was analyzed using a Monte Carlo method, and the reliability of the BLDC motor was obtained using a statistical method according to the fault criterion. The dual response surfaces analysis method could optimize the performance and reliability simultaneously, providing a new method for the analysis of a motor.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"271 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":"116188696","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}
