However, the interaction among the permanent magnets on the each part can inevitably produce cogging torque and torque ripple, which may cause noise and vibration. In this paper, a new design method to reduce the cogging torque is presented for the magnetic planetary gearbox. In order to achieve the goal of minimizing the cogging torque and maximizing the transmission efficiency, a global optimization algorithm and the finite element analysis (FEA) are integrated to obtain the best pole arc combination. In the process of size optimization, two optimization methods, single parameter independent optimization and Quasi Newton optimization, are applied respectively. The investigation results indicate that by using the two kinds of optimization algorithm, the cogging torque and torque ripple can be reduced significantly while the transmission efficiency can be greatly improved.","PeriodicalId":119598,"journal":{"name":"2013 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124196155","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}

Due to its merits of simplicity, high robustness, low cost, and flexible control, the DS-BLDCG is suitable for the automobile auxiliary power unit (APU) application. Since no constraint is imposed to the number of phases of the onboard brushless dc generator, the polyphase DSEG can be applied. In this paper, a 3-phase 12/8-pole DSEG and a 4-phase 16/12-pole DSEG for the APU application are proposed. The taper stator pole and broadened rotor pole structure utilized to increase maximum output power is introduced in the 4-phase DSEG design. Based on the two-dimensional finite-element method (FEM) and field-circuit coupling analysis, a comprehensive comparison is presented. The 16/12-pole DS-BLDCG exhibits better fault tolerant capability, lower voltage ripple, and higher output power, while the copper consumption of the 12/8-pole DS-BLDCG is less than the 16/12-pole one. A prototype 12/8-pole DS-BLDCG for the APU applica-tion is designed and developed. Both the simulation and experimental results indicate that the developed DS-BLDCG is a promising option for automobile APU application.","PeriodicalId":119598,"journal":{"name":"2013 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129415630","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}

SDPM can be utilized for direct-driving areas by the advantages of the high torque density and high efficiency. In this paper, the key is the halbach array is not traditional and can be optimized, it can offer higher effective harmonic components of the magnetic field as well as the pull-out torque than the radial magnetized self-decelerating permanent-magnet (RSDPM) motor. In addition, the adoption of halbach arrays can reduce the flux density of the rotor yoke, the Iron losses can be reduced too.

But implementing and testing applications or protocols in real world require prohibitive costs. Hence, most of the related researches depend on simulations. And mobility model is one of the most critical issues in the simulation study of VANETs. In this paper, we present a vehicular mobility model called ADM (Accident Driver Model) based on the concept of IDM (Intelligent Driver Model) to mimic the non-standard driver behaviors, and make the mobile nodes create accidents actively, while most of the mobility models don't support this feature. Then we implement ADM on the open-source traffic simulator VanetMobiSim. Finally, we investigate the influences of different mobility models on the performance of VANETs routing protocol. The simulation results show that we can evaluate routing performance correctly with ADM.","PeriodicalId":119598,"journal":{"name":"2013 IEEE Vehicle Power and Propulsion Conference (VPPC)","volume":"15 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127648788","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}
