In this paper, an architecture design method based on MBSE applied in aircraft cabin pressure control system is introduced. A top-down design process including functional physical architecture analysis is presented to ensure final solution can meet stakeholder needs. Functional architecture produced by functional analysis which transfers stakeholder needs and top-level requirements to design requirements has great effects on physical solution design. Physical architecture which is implementation of functional architecture provides enough detail to synthesize a physical architecture. This paper proposes a framework for efficient architecture based MBSE which can also provide common understanding of the scope and characterization of the system for engineers involved in system design. It shows that the proposed MBSE method significantly improves synthesis of design and integration, and ensure the requirements can be properly implemented","PeriodicalId":374943,"journal":{"name":"2021 7th International Conference on Mechanical Engineering and Automation Science (ICMEAS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117000765","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}

Hence, teleoperated robots with robotic arms have been proposed to execute any tasks that appointed. However, most robotic arms on the teleoperated robots only serve specific tasks and have no ability to retract arm with precise and smooth movement, which will compromise its functionality. In this paper, five designs of robotic arms were proposed with different mechanisms for its retractions. Evaluation and selection for the final design was decided based on the decision-making process for all designs. Considering important criterion, evaluation was performed using concept scoring. All concept designs were modelled and analysed in SolidWorks. Load was applied on the end effector of robotic arm to observe Von Mises criteria of designed arms. Both methods indicate that design 5 with linear motor mechanism has the best endurance and thus, chosen as the most suitable design to be mounted on the track vehicle.","PeriodicalId":374943,"journal":{"name":"2021 7th International Conference on Mechanical Engineering and Automation Science (ICMEAS)","volume":"49 3-4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123456739","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}

However, traditional data-driven methods assume that the collected data following identical distribution and the training data is sufficient, which is impractical in practice. This paper proposed a novel framework to realize tool wear monitoring across scenarios based on deep transfer learning. The collected multi-source heterogeneous signal is fused based on the feature self-extraction and selection capabilities of deep learning. Particularly, the feature extraction capability of convolutional neural networks (CNN) for structured data is improved by integrating traditional feature extraction methods. Furthermore, the transfer learning technique is introduced to migrate the pre-trained model from the source domain to the target domain, and thus achieving the tool wear monitoring across scenarios. The proposed framework was applied to the continuous cutting process of tools and the excellent experimental results demonstrated the effectiveness of the deep transfer learning network for tool wear monitoring with a small number of labeled data, which demonstrates the practicality of the proposed framework.","PeriodicalId":374943,"journal":{"name":"2021 7th International Conference on Mechanical Engineering and Automation Science (ICMEAS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126210858","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 proposes a vision-based relative navigation sensor for OOS of CubeSats. A set of active fiducial markers with multi-layer structure was designed to ensure an accurate unambiguous matching and measurement. An improved effective perspective-n-point (IEPnP) algorithm is developed to obtain an accurate relative state estimation. An experiment system which simulates the real illumination and motion conditions in space was set up to assess the performances of the proposed sensor. The results show that the sensor can overcome the interference of the ambient light, and can reach an accuracy of range estimation smaller than 2 mm and an accuracy of relative attitude estimation smaller than 0.4 deg at distance of 1 m. Through contrast tests, the accuracy of the proposed IEPnP algorithm is better than the classical perspective-3-point (P3P) algorithm and EPnP algorithm.","PeriodicalId":374943,"journal":{"name":"2021 7th International Conference on Mechanical Engineering and Automation Science (ICMEAS)","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132549201","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}
