灰色关联法的装甲车辆混合电传动方案评估

为了实现装甲车辆混合电传动系统方案的优化设计,在综合运用层次分析法和灰色关联分析法的基础上,建立了一个新型的综合评价模型。模型采用层次分析法确定评价指标的权值,运用灰色关联分析法计算评价对象的灰色关联系数,进而计算加权灰色关联度作为判定评价对象优劣的准则。最后利用该模型对4种主流混合电传动方案的评估,得到了混合电传动方案性能优劣的排序,并对排序结果进行了分析。     

混合动力装甲车辆能量管理策略实时仿真

为解决混合动力装甲车辆多动力源输出优化匹配难题,针对一种具有3个动力源的混合动力系统中各动力源的输出特性和驱动电机功率需求特点,制定了具有双层结构的能量管理策略:顶层的系统功率分配策略完成负载功率估计及其在各动力源间的分配;底层的部件级控制策略实现发动机-发电机组和动力电池的优化控制。通过构建一种分布式硬件在环仿真平台对能量管理策略进行仿真验证。结果表明:混合动力系统能够很好地满足负载功率需求,实现了对多个目标的优化控制。     

Study on Modeling and Control Strategy for Electric Drive Motor of Tracked Vehicles

Aimed at the requirements for electric transmission system of a military tracked vehicle, the motor's design indexes were analysed and calculated. A model based on saturate inductance parameter of interior permanent magnet (IPM) synchronous motor was brought forward by using finite element analysis. And its control strategy based on the largest running capability was studied also. The experiment results for a scale model show that the modelling method improves the model's accuracy, and the motor's control strategy is effective.
