The results show that there is only bainite transformation region during the continuous cooling process. When the cooling rate is low, the microstructure is mainly granular bainite with a small amount of ferrite and the hardness of microstructure is only about 270HV. With the increase of cooling rate, the ferrite disappears, the microstructure transforms from fully granular bainite to lath bainite, and the hardness of microstructure also increases. When the cooling rate is above 10°C/s, the microstructure is all lath bainite, and the hardness of microstructure also reaches a maximum of about 360HV.","PeriodicalId":155375,"journal":{"name":"2020 3rd International Conference on Electron Device and Mechanical Engineering (ICEDME)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115364670","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}

Firstly, the mathematical model of the multi disk PMSM is established, and the efficiency optimization control strategy based on the efficiency map is proposed, and the efficiency optimization control method of the multi disk PMSM is analyzed. Secondly, on the basis of efficiency optimization, a torque collaborative control strategy is proposed, in which fuzzy control is used to optimize the torque fluctuation. Finally, the simulation analysis and vehicle test are carried out for the proposed control strategy. The results show that the modular multi disk PMSM collaborative optimization drive system has a wider range of high efficiency, widens the system efficiency platform, increases the range, and improves the system motion characteristics, which has significantly theoretical research significance and application value.","PeriodicalId":155375,"journal":{"name":"2020 3rd International Conference on Electron Device and Mechanical Engineering (ICEDME)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116579007","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}

A series of creep tests of multiple crumb rubber asphalt sand samples were carried out to determine the parameters samples. Based on the statistical analysis, the random parameter is determined and the normal distribution is used to describe the distribution law of the parameter to determine the random constitutive model. Finally, a random loading experiment was carried out to predict and verify the proposed model. The results show that the proposed the model parameter is more representative and can predict the deformation range of crumb rubber asphalt sand under other stress loading history.

The output torque signals in mechanical fault condition of the disconnector were analyzed, including the case of jammed transmission mechanism, balance spring failure and incompletely switch - on. The clamping stagnation diagnosis process was proposed. The results indicate that the torque waveform of the operating mechanism may distort when mechanical faults occur on the disconnector, the peak value will increase, and the peak time will shift. Through the simulation calculation and field test proving the study of disconnector switch mechanical breakdown to curve influence, a set of expert diagnosis system is designed for carrying out expert judgment objectively and accurately in order to determine the abnormal position. This method is of general applicability and can effectively detect mechanical faults of disconnector, so as to improve the operational reliability of power equipment.","PeriodicalId":155375,"journal":{"name":"2020 3rd International Conference on Electron Device and Mechanical Engineering (ICEDME)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125436182","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 general, in the low temperature range, the calculated molar heat capacity at constant pressure is in good agreement with the available experimental data, but in the high temperature range, the calculated results and the available experimental value are quite different, which is caused by anharmonic effect, and the sample itself will produce more defects at high temperature.","PeriodicalId":155375,"journal":{"name":"2020 3rd International Conference on Electron Device and Mechanical Engineering (ICEDME)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124010426","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}
