At present, the EMU manufacturers still adopt the idea of traditional system engineering to decompose the requirements, resulting in the lack of traceable links between requirements and design, which seriously prolongs the product development cycle and increases the development cost. Under this background, this paper introduces the idea of model-based systems engineering (MBSE) into the EMU requirements management. The method is vertically divided into four aspects: the L1 layer is customer requirements, the L2 layer is product requirements, the L3 layer is system requirements, and the L4 layer is component requirements; the horizontal activities are divided into five steps: requirements capture, requirements analysis, requirements confirmation, requirements allocation, and requirements verification. It is applied to the requirements management of EMUs air conditioning system, and the results show that the application of MBSE to EMUs requirements management can establish the traceability relationship between requirements and design, ensure the accuracy of requirements, improve the efficiency of requirements management, and realize the transformation of EMU requirements from “document based” to “model-based”.","PeriodicalId":212840,"journal":{"name":"Conference on Smart Transportation and City Engineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130580886","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}

As an important structural form of crossing water, immersed tunnel has been paid more and more attention. However, the joints between precast segments of immersed tunnel, especially the final joints of the closure section, are the key problems in the construction of immersed tunnel, where there are multi-directional needs such as permeability, safety, convenience and economy. The final joint technology in the construction of large immersed tunnel, such as Shenzhen-Zhongshan Link, is a controlling problem, and innovative technology is still needed. In this paper, five kinds of final joint structures and construction methods of immersed tunnel are investigated, and the characteristics of each joint are summarized and introduced. The final joint forms in the existing representative projects in China are also investigated and summarized. Finally, on the basis of the existing research, the problems that need to be paid attention to in the construction of the final joint of Shenzhen-Zhongshan Link are pointed out, which provides a reference for the construction of similar projects.","PeriodicalId":212840,"journal":{"name":"Conference on Smart Transportation and City Engineering","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132550681","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 this paper, finite element software ANSYS was used to establish finite element model of transmission tower, three towers and four-wire finite elements of ordinary steel core aluminum strand and carbon fiber composite core conductor, which calculates the displacement, axial force and bending moment of the transmission single tower, the ordinary steel core aluminum strand before the transformation and the carbon fiber composite core wire tower system after the transformation. The analysis results show that the top displacement of the tower, in the tower line coupling system of ACCC conductor, is about 48.9% higher than that of the transmission tower, and the axial force and bending moment of the bottom of the tower, are about 39.6% and 37.9% higher than that of the transmission single tower, which indicates that the coupling of the tower line needs to be considered when the ACCC wire is used for the transmission line. The maximum displacement of the tower top under the ACCC wire is reduced by about 62.7%, compared with the maximum displacement of the tower top under the action of the ACSR wire, and the maximum axial force and bending moment of the bottom of the tower are also reduced by about 64.2% and 64.7% , which explains that the carbon fiber composite core wire after the transformation has more superior performance than the ordinary steel core aluminum stranded wire used for transmission lines before the transformation.","PeriodicalId":212840,"journal":{"name":"Conference on Smart Transportation and City Engineering","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124275277","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}

How to ensure environmental safety through safe transportation management and effective disposal of spent fuel is a new social proposition that needs to be considered and discussed in environmental protection. Based on the Web of Science database, the bibliometric tool Histcite is used to carry out a systematic metrological analysis of the research on spent fuel transportation, compares the status and priorities of spent fuel transportation research at home and abroad, grasps the current research trends and hot issues, and analyzes the development status of spent fuel transportation safety based on trend analysis. The research results show that the research related to spent fuel transportation first started in 1972 and the number of documents is increasing; the M-K trend test analysis results also show that there are obvious mutations in the related research. The internationally influential units in the field of spent fuel transportation are mainly concentrated in European and American countries such as the United States and Sweden, and the quality of the literature is high, and they are in an international leading position. The whole process of transportation assessment and environmental risk simulation are the research hotspots in this field.","PeriodicalId":212840,"journal":{"name":"Conference on Smart Transportation and City Engineering","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116899136","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 recent years, a large number of highway tunnels have been put into use. The prevalence of water seepage diseases in road tunnels poses a major hazard to the safety of personnel and vehicles. Water seepage detection has been one of the high-priority research topics for tunnel inspection. Previous studies have mainly used a single visible camera as a sensor to detect water leakage areas in images, which is extremely sensitive to insufficient lighting in the tunnel. Considering the existence of temperature difference between the water leakage area and the normal area, we used an infrared camera to collect tunnel lining images and constructed a water leakage area identification algorithm based on the temperature difference between the water leakage area and the normal area using K-means clustering algorithm and low-pass filtering algorithm based on the temperature field distribution of infrared images. This study can provide a new idea for the rapid identification of tunnel water leakage.","PeriodicalId":212840,"journal":{"name":"Conference on Smart Transportation and City Engineering","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126526079","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}
