串联式混合动力码头车的结构形式及控制方案的选择.doc

摘 要 混合动力汽车近年来发展迅速，并已经实现了产业化。混合动力汽车将至少在30年内都是汽车工业最切实可行的解决能源和污染问题的途径。码头牵引车运行速度低，起停频繁，且长时间怠速，导致其燃油经济性差，排放高。研制成混合动力码头牵引车后，其节油减排效果较其它车辆更为明显。本文利用汽车相关理论通过计算机分析仿真来确定混合动力码头牵引车的驱动电机的参数。 分析与仿真的主要作用是在进行昂贵且费时的原型实验之前对物理系统的性能进行模拟分析，工程设计人员可以利用它全面地评估其设计，并通过它发现设计中的一些问题，而这些问题通过测量和实验是不易发现的。分析与仿真技术不仅可以节省大量开发费用，而且提高了复杂系统的系统级优化水平。对于混合动力研发，前期进行方案选择及参数匹配时，通过分析仿真能够较快地进行方案选择及参数匹配，从而确定最优方案和主要参数，并及早发现问题加以避免。若通过试制实物样机的方法来进行此步骤，则既费时又费力，代价昂贵，且效果还不好。在研发过程中分析仿真与试验同样重要，都具有不可替代的作用，通过实物样机试验对分析仿真结果进行验证与修正，对系统反复优化，从而有力地推进研发进程。 关键词：混合动力码头牵引车，驱动电机参数，车辆动力性分析 ABSTRACT Hybrid electric vehicle developed rapidly in recent years and has achieved industrialization. Hybrid Electric Vehicle will be at least 30 years in the automotive industry are the most practical solution to energy and pollution problems. Low-speed terminal tractor, since the frequent stops and idling time, resulting in poor fuel economy, emissions high. The development of hybrid terminal tractor, its fuel-efficient vehicle emission reduction effect is more obvious than the other. In this paper, the use of motor vehicle-related theory by computer simulation analysis to determine the hybrid electric terminal tractor driver parameters. The analysis and the simulation leading role is before carrying on expensive and the time-consuming prototype experiment to physical systems performance carries on the simulation analysis, the engineering design personnel may use it to appraise its design comprehensively, and discovers in the design through it some questions, but these questions through the survey and the experiment are which is not easy to discover. The analysis and the emulation technique not only may save the massive development cost, moreover raised complicated systems system-level optimization level. Regarding the mix power research and development, when the earlier period carries on the plan choice and the parameter match, through the analysis simulation can quickly carry on the plan choice and the parameter match, thus determined that the s
