| 2 | Design System of the Two-step Gear Reducer on Case-based Reasoning显示文摘The design of the two-step gear reducer is a tedious and time-consuming process.For the purpose of improving the efficiency and intelligence of design process,case-based reasoning(CBR) technology was applied to the design of the two-step gear reducer.Firstly,the current design method for the two-step gear reducer was analyzed and the principle of CBR was described.Secondly,according to the characteristics of the reducer,three key technologies of CBR were studied and the corresponding methods were provided,which are as follows:(a) an object-oriented knowledge representation method,(b) a retrieval method combining the nearest neighbor with the induction indexing,and(c) a case adaptation algorithm combining the revision based on rule with artificial revision.Also,for the purpose of improving the credibility of case retrieval,a new method for determining the weights of characteristics and a similarity formula were presented,which is a combinatorial weighting method with the analytic hierarchy process(AHP) and roughness set theory.Lastly,according to the above analytic results,a design system of the two-step gear reducer on CBR was developed by VC++,UG and Access 2003.A new method for the design of the two-step gear reducer is provided in this study.If the foregoing developed system is applied to design the two-step gear reducer,design efficiency is improved,which enables the designer to release from the tedious design process of the gear reducer so as to put more efforts on innovative design.The study result fully reflects the feasibility and validity of CBR technology in the process of the design of the mechanical parts. | JI Aimin HUANG Quansheng XU Huanmin CHEN Zhengming | 2009 | Chinese Journal of Mechanical Engineering2009，22，5： | 6 |

| 14 | Design and parameters optimization for cutting-conveying mechanism of ramie combine harvester显示文摘In order to solve the problems of uneven stubble,low cutting efficiency and frequent breaking and blocking in the cutting and conveying links of ramie combine harvester,a reciprocating double movable blades cutter and a double-layer chain conveyor were designed,and the operating parameter test and optimization were carried out by using the central combination test design theory,with the emphasis on the influence of the forward speed,the cutting speed of the cutter and the conveying speed of the chain on the cutting efficiency,the failure rate and the conveying rate,and the multi-objective optimization was carried out based on these response indicators.Firstly,the structure and operating parameters of the cutting-conveying mechanism of ramie combine were studied.Then,the experiment was designed by the quadratic orthogonal rotation combination test method,and the data is processed by Design-Expert.The regression mathematical model of cutting efficiency,failure rate and conveying rate was established and variance analysis was carried out.By analyzing the effect of interaction of various factors on cutting efficiency,failure rate and conveying rate by response surface methodology,and performing multi-objective optimization on the regression model according to the importance of the optimization target,the optimal combination of the operating parameters of the cutting-conveying parts of the ramie combine harvester was obtained:when the forward speed was 0.85 m/s,the cutting speed was 1.40 m/s,and the chain conveying speed was 1.33 m/s,the cutting efficiency and conveying rate were the maximum and the failure rate was the minimum,with the values of 44.36 plants/s,93.60%and 4.16%,respectively.The optimized parameters were verified in the field on the ramie combine harvester.In the field test,the cutting efficiency,conveying rate,and failure rate were 43.80 plants/s,92.45%,and 4.52%,respectively,and the relative errors with the optimized values were 1.3%,1.2%,and 8.7%,respectively,which was relatively consistent. | Jicheng Huang Kunpeng Tian Cheng Shen Bin Zhang Haolu Liu Qiaomin Chen Xianwang Li Aimin Ji | 2020 | International Journal of Agricultural and Biological Engineering2020，13，6： | 1 |

| 17 | Design and experiment of the bionic disc cutter for kenaf harvesters显示文摘Aiming to ease the cutting of kenaf stalks via bionics,the bionic disc cutter was designed.The upper jaw of the Batocera horsfieldi was used as a bionic prototype.Further,to explore its dynamic performance,an indoor multi-stalk cutting experimental bench was used to simulate the field operation process.A three-factor and two-level interaction orthogonal experiment was carried out;cutting speed,stalk conveying speed(machine forward speed),and blade type(ordinary disc cutter and bionic disc cutter)were used as experiment factors.The cutting pass rate and cutting specific energy consumption were selected as evaluation indexes.The range,variance,and fuzzy comprehensive evaluation analysis were carried out on the experiment results.Moreover,the main order factors affecting the bionic cutter performance were determined-blade type,conveying speed,the interaction between the cutter speed and conveying speed,and cutter speed.The optimal parameter combination scheme had a cutter speed of 1000 r/min,conveying speed of 0.4 m/s,and included bionic blades.Under this condition,the best index was the 92%cutting pass rate,with a specific energy consumption of 4.38 J/stalk.The variance analysis has shown that,with 95%confidence,the blade type has a rather significant influence on the comprehensive index.Additionally,the conveying speed also significantly influenced it,while other factors and interactions had no notable effect.The experimental comparison under the same working condition shows that the bionic blade has better cutting effect.This study provides a reference for the development of cutter and the selection of kenaf harvester operational parameters. | Kunpeng Tian Bin Zhang Aimin Ji Jicheng Huang Haolu Liu Cheng Shen | 2023 | International Journal of Agricultural and Biological Engineering2023，16，6： | 0 |
| 18 | Formation mechanism for the laying angle of hemp harvester based on ANSYS-ADAMS显示文摘Aiming at the problem of large differences in the laying angle and posture of plants cut by the hemp harvester,which is unfavorable for the subsequent picking-up,this paper analyzed the laying process and laying angles,and built a conveyorplant rigid-flexible coupling model for simulating the laying of hemp plant.Moreover,the operating parameters were tested and optimized based on the central composite design theory,and carried out multi-objective optimization with the minimum laying angle as the response index.Firstly,the formation mechanism of the laying angle of hemp harvester was studied.Secondly,a test was designed with the quadratic orthogonal rotational combination test method,with the data being processed by Design-Expert.A regression mathematical model of the laying angle was built,and the influence of the interactions between factors on the laying angle was analyzed with the response surface method.Furthermore,multi-objective optimization was conducted on the regression model according to the actual production design requirements.As a result,the best combination was obtained,that is,when the forward speed is 0.7 m/s,speed ratio 1.40,and stubble height 95 mm,the minimum laying angle can be obtained,namely 124.9°.The optimization parameters were verified by the simulation and field tests.The simulation test showed that the simulated laying angle is 125.2°,with a relative error of 0.24%from the theoretical value,under the best combination of parameters.The field test showed that the average laying angle of hemp plant is 121.8°,with a relative error of 2.5%from the theoretical value,under the best combination of parameters.The results may provide a reference for the structural improvement and operating parameter control of hemp harvesters. | Jicheng Huang Li Tan Kunpeng Tian Bin Zhang Aimin Ji Haolu Liu Cheng Shen | 2023 | International Journal of Agricultural and Biological Engineering2023，16，4： | 0 |
| 19 | Rapid screening of magnetic properties in several Fe-X-Ni systems via combinatorial materials chip method显示文摘Fe-X-Ni(X=Cr,W and V)combinatorial thin-film(∼100 nm thick)materials chips covering the full composition range of ternary systems were fabricated.The crystal structure distribution was mapped by micro-beam X-ray diffractometers(XRD)and the magnetic hysteresis loops over the chip were characterized by a high-throughput magneto-optical Kerr effect(HT-MOKE)system to establish the composition-phase-magnetic properties relationships.The results showed that saturation magnetization for all systems has a strong dependency on alloying composition,and decreases with increasing dopped elements content as a general trend.Although the trend of saturation magnetization in bulk is in good agreement with that from thin films,all bulk samples show almost no coercivity,attributable to the much smaller grain size,and stronger texture in thin-film samples.Comparing the Fe-X-Ni systems under a similar condition,in the out-of-plane,Cr alloying obtained the largest coercivity(∼400 mT)followed by W alloying(∼300 mT)and then V alloying(∼200 mT).We suggest that alloying with different elements leads to the diverse orientation and crystallinity of the fcc phase resulting in different magnetic properties.Meanwhile,the effect of heat treatment on magnetic properties indicates that saturation magnetization is more closely related to the duration of heat treatment. | Cai Chen Xinyi Ji Jianhao Wang Mei Liu Yao Lu Xiaoping Wang Aimin Zhang Li Chen Xianping Dong Lanting Zhang Hong Wang | 2023 | Journal of Materiomics2023，9，1： | 0 |
| 20 | Application of meta-learning in cyberspace security:a survey显示文摘In recent years,machine learning has made great progress in intrusion detection,network protection,anomaly detection,and other issues in cyberspace.However,these traditional machine learning algorithms usually require a lot of data to learn and have a low recognition rate for unknown attacks.Among them,“one-shot learning”,“few-shot learning”,and“zero-shot learning”are challenges that cannot be ignored for traditional machine learning.The more intractable problem in cyberspace security is the changeable attack mode.When a new attack mode appears,there are few or even zero samples that can be learned.Meta-learning comes from imitating human problem-solving methods as humans can quickly learn unknown things based on their existing knowledge when learning.Its purpose is to quickly obtain a model with high accuracy and strong generalization through less data training.This article first divides the meta-learning model into five research directions based on different principles of use.They are model-based,metric-based,optimization-based,online-learning-based,or stacked ensemble-based.Then,the current problems in the field of cyberspace security are categorized into three branches:cyber security,information security,and artificial intelligence security according to different perspectives.Then,the application research results of various meta-learning models on these three branches are reviewed.At the same time,based on the characteristics of strong generalization,evolution,and scalability of meta-learning,we contrast and summarize its advantages in solving problems.Finally,the prospect of future deep application of meta-learning in the field of cyberspace security is summarized. | Aimin Yang Chaomeng Lu Jie Li Xiangdong Huang Tianhao Ji Xichang Li Yichao Sheng | 2023 | Digital Communications and Networks2023，9，1： | 0 |
