| 1 | Design of Rotor Magnetic Barrier Structure of Built-in Permanent Magnet Motor Based on Taguchi Method显示文摘In this paper,a 20kW vehicle built-in permanent magnet synchronous motor is taken as an example,and a magnetic barrier structure is added to the rotor of the motor to solve the uneven saturation problem of the rotor side magnetic bridge.This structure improves the air-gap flux density waveform of the motor by influencing the internal magnetic flux path of the motor rotor,thus improving the sine of the no-load back EMF waveform of the motor and reducing the torque ripple of the motor.At the same time,Taguchi method is used to optimize the structural parameters of the added magnetic barrier.In order to facilitate the analysis of its uneven saturation phenomenon and improve the optimization effect,a simple equivalent magnetic network(EMN)model considering the uneven saturation of rotor magnetic bridge is established in this paper,and the initial values of optimization factors are selected based on this model.Finally,the no-load back EMF waveform distortion rate,torque ripple and output torque of the optimized motor are compared and analyzed,and the influence of magnetic barrier structure parameters on the electromagnetic performance of the motor is also analyzed.The results show that the optimized motor can not change the output torque of the motor as much as possible on the basis of reducing the waveform distortion rate of no-load back EMF and torque ripple. | Shengnan Wu Xianwen Pang Wenming Tong Yingcong Yao | 2023 | CES Transactions on Electrical Machines and Systems2023，7，2： | 0 |
| 2 | Research Progress of Anaerobic Digestion Pretreatment of Antibiotic Waste显示文摘Anaerobic digestion is one of the effective ways to dispose of antibiotic pharmaceutical waste. However,the inhibition of antibiotics on anaerobic fermentation microorganisms seriously hinders the normal physiological activities of anaerobic microorganisms and then affects the efficiency of anaerobic digestion. In order to solve this problem,related scholars have done a lot of research. It has been found that pretreatment of anaerobic microorganisms and antibiotic pharmaceutical waste can significantly improve the efficiency of anaerobic digestion. In this paper,the current feasible pretreatment methods were summarized,and the application of different pretreatment methods was analyzed to provide reference for improving pretreatment methods and improving anaerobic biological treatment ability of antibiotic waste. | Shengnan ZHAO Yanru CUI Hai GAO Yeming ZHAO Fengxian PANG Xiaodong CHENG Jiao XIE Xin WANG Wei OU | 2018 | Asian Agricultural Research2018，10，5： | 0 |
| 3 | Blended Teaching Mode Based on“Cloud Class+PAD Class”in the Course of Computer Graphics and Image Design显示文摘As a teaching tool,Cloud class is specially developed for teaching and learning in mobile circumstance,and the PAD(Presentation Assimilation Discussion)class acts as a creative teaching mode.The combination of Cloud class and PAD class helps build online-offline blended teaching model.In this paper,a Cloud+PAD class mode is proposed.An experiment of teaching is implemented and the practical effectiveness is evaluated and verified.The experimental results show,compared with the conventional teaching method,the proposed teaching mode is capable of creating more high-level,innovative and complex teaching content,and thereby noticeably enhancing students’learner autonomy and motivating them to develop creativity. | Yuhong Sun Shengnan Pang Baihui Yin Xiaofang Zhong | 2020 | 国际计算机前沿大会会议论文集2020，，2： | 0 |
