Locomotives, as an important part of the rail transportation industry, are typical complex technical equipment with a long-life cycle and require multiple overhaul work during the life cycle to ensure safe operation. At the same time, because of the complex structure of locomotive products, high operational reliability requirements, large downtime losses, and many levels of maintenance, simple maintenance processes are not applicable. The Intelligent Transportation System (ITS) can monitor and detect the traffic information parameters in real time, so the ITS is used to troubleshoot locomotives and enable them to operate safely. It can be seen from this study that the application of intelligent transportation system in Locomotive Maintenance (LM) can be used as locomotive maintenance engine and monitor the maintenance process to keep the locomotive running well.","PeriodicalId":290902,"journal":{"name":"International Conference on Mechatronics Engineering and Artificial Intelligence","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133941460","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}

Lou","doi":"10.1117/12.2672147","DOIUrl":"https://doi.org/10.1117/12.2672147","url":null,"abstract":"Side pole impact is a common form of road traffic accident. Due to the narrow side energy absorption space, the development of the vehicle side restraint system has put forward strict requirements. However, the reappearance accuracy of side pole impact sled in the industry is always at a low level, and enterprises can only choose expensive real vehicle tests or CAE methods for development. In this paper, a multi-cylinder intrusive side pole sled impact test method is proposed. Through the coupling and decoupling of the pulses between the main sled and the side impact sled, the interaction process between the door and the dummy in the real vehicle impact test is well simulated, and the V-type intrusion is realized. The data after the test is analyzed in detail. The chest ribs and abdominal ribs of the dummy show good consistency, and the deviation can be controlled within 15%, which greatly reduces the development cost of the side pole impact. At the same time, there are also deviations in the compression amount of the upper rib and the force of the pubic symphysis force, which can be continuously optimized in the follow-up work. This research provides a new idea and solution for the development of the side restraint system.","PeriodicalId":290902,"journal":{"name":"International Conference on Mechatronics Engineering and Artificial Intelligence","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131855414","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}

Wire and Arc Additive Manufacturing has the advantages of high material utilization, high molding efficiency, low equipment cost and unlimited size of molded parts, etc., which has received wide attention from scholars in various countries. However, poor forming accuracy limits the development of this technology. In this paper, a quadratic regression model between weld pass size and welding voltage, welding current and welding speed was established by using the quadratic universal rotary assembly experiment method in single-layer single-pass Wire arc additive manufacturing test.

In this study, two machine learning methods, random forest (RF) and support vector machine (SVM), were used to study the strength of low-alloy steels on the existing data samples of low-alloy steels, so as to make relevant predictions on their strengths and find the most influential factors. Comparing the measured results with the predicted values shows that RF outperform SVM in predicting results. And by calculating the correlation coefficient, the two features that have the greatest influence on the strength are the temperature and the content of V, respectively. This result can be used to optimize the properties of low-alloys.","PeriodicalId":290902,"journal":{"name":"International Conference on Mechatronics Engineering and Artificial Intelligence","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116776477","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}

Communication technology is the key technology of UAVs, which has a decisive impact on the development of UAVs. The 5G cellular network also brings more possibilities to UAVs. With the rapid development of 5G cellular-connected drones, the security issues of their sensor networks have also attracted widespread attention. This paper studies the key management technology in the 5G network-connected UAV sensor network. Although public key encryption schemes such as RSA and elliptic curves can provide sufficient security, their applications are limited due to their extremely high demands on computing power, which conflict with the resource constraints of sensor nodes. For the security management of cluster keys, this paper introduces the concept of bivariate polynomials into key management. This not only ensures pairwise keys between any two nodes, but also performs intercluster key distribution on the generated bivariate polynomials, tests various characteristics of the generated bivariate polynomials in key management, and Simulation experiments are carried out under different orders of polynomials.","PeriodicalId":290902,"journal":{"name":"International Conference on Mechatronics Engineering and Artificial Intelligence","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121802877","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}
