| 1 | 电动汽车差动助力转向与主动前轮转向协调控制显示文摘装备差动助力转向(DDAS)系统的汽车匹配主动前轮转向(AFS)系统时,两者会相互干扰。DDAS助力时引入的横摆力偶矩会影响车辆的转向特性,反之,AFS的介入会导致转向盘转矩突变。为此,本文提出了一种差动协同主动转向(DDCAS)系统。首先,介绍了DDCAS系统的结构和动力学模型;然后,分别制定了DDAS和AFS的控制策略,分析了两系统的干扰机理,并制定了DDCAS控制策略。最后,在Matlab/Simulink与CarSim联合仿真平台上进行了典型工况的仿真分析,验证了本文控制策略的有效性。 | 王军年 郭德东 颜庭旭 Assadian Francis 罗正 | 2020 | 吉林大学学报(工学版)2020，50，3： | 6 |
| 2 | Simulation investigation of tractive energy conservation for a cornering rear-wheel-independent-drive electric vehicle through torque vectoring显示文摘Although electric vehicle fully exhibits its comparative merits of energy conservation and environmental friendliness, further improvement of its traction energy efficiency lacks comprehensive investigations in the past. In this paper, the effect of the torque vectoring on traction energy conservation during cornering for a rear-wheel-independent-drive electric vehicle is investigated.Firstly, turning resistance coefficient and energy conservation mechanism of torque vectoring are derived from the single track dynamic model. Next, an optimal torque vectoring control strategy based on genetic algorithm is proposed, with the consideration of the influence of the operation-point change of the in-wheel motors, to find out the best torque vectoring ratio offline. Finally,various simulation tests are conducted to validate the energy conservation effect after Simulink modelling. The results verify that though the optimization of the operating region of the motors is the main part for tractive energy conservation, the contribution of torque vectoring itself can reach up to 1.7% in some typical cases. | SUN Wen WANG JunNian WANG QingNian ASSADIAN Francis FU Bo | 2018 | Science China(Technological Sciences)2018，61，2： | 5 |
| 3 | 电动汽车转矩定向分配差速器建模与动态仿真显示文摘本文中提出一种新型具备转矩定向分配功能差速器的集中式电驱动桥系统。该集中驱动系统可以在不改变总驱动转矩的条件下,类似分布式驱动方式实现驱动转矩在左右轮间的任意分配,从而产生改变车辆横摆动力学的直接横摆力偶矩。首先,分析了转矩定向分配差速器结构特点及其工作原理;其次,利用键合图理论建立了其动力学模型,并仿真分析了其动态响应特性;然后,设计了转矩响应控制系统以改善该差速器的动态性能;最后,嵌入整车模型进行了联合仿真。结果表明,装备该差速器的车辆可任意分配左右轮驱动转矩,并有效改善车辆操控特性。 | 王军年 倪健土 杨斌 Francis Assadian | 2020 | 汽车工程2020，42，4： | 4 |
| 4 | 固溶处理对可生物降解Mg-6Zn合金腐蚀性能的影响(英文)显示文摘对可生物降解二元Mg-6Zn合金进行固溶处理,来评价获得的显微组织变化对合金降解速率的影响及其相关机理。在350°C条件下固溶处理6-48 h。采用光学显微镜、扫描电镜、能量色散X射线光谱仪和X射线衍射仪分析铸态和固溶处理后试样。在37°C的模拟体液中进行浸泡和电化学测试,评价其抗腐蚀性。为保证腐蚀测试的结果,对p H值进行测试。结果发现,大于24 h的固溶处理,金属间化合物相溶解于基体中,并产生了近单晶相组织。金属间化合物相的减少导致阴极区/阳极区比减小且腐蚀率降低。电化学和失重测试结果表明,延长固溶处理时间可提高合金的抗腐蚀性。经350°C固溶处理24 h后,铸态合金的抗腐蚀性提高了60%以上。另外,逐渐减少的金属间化合物相和伴随的低p H值上升,降低了腐蚀速率。对于Mg-Zn合金作为生物可降解移植材料的应用,固溶处理是一种可以提高腐蚀性的工艺。 | Seyed Morteza Ghaffari SHAHRI Mohd Hasbullah IDRIS Hassan JAFARI Babak GHOLAMPOUR Mahtab ASSADIAN | 2015 | Transactions of Nonferrous Metals Society of China2015，25，5： | 3 |
