【摘要】：面对全球能源危机和环境污染的巨大挑战,发展新能源车辆与工程机械,实现车辆与工程机械节能减排,推动传统产业战略转型,在国际上已经形成了广泛共识。近年来,随着我国经济的不断发展和城市化进程的不断加快,工程机械产业得到了快速发展。工程机械所面临的节能减排压力也日益严峻。传统柴油叉车作为广泛应用的工程机械,运行工况及负荷变化大且频繁,采用混合动力系统对叉车节能减排具有重要的意义。本文以3吨混合动力叉车为研究对象。首先在全面分析叉车运行工况的基础上,提出了叉车运行简化工况和运行特点。然后综合分析并比较了混合动力车辆各种构型特点,提出了单轴并联式叉车混合动力构型方案。对叉车混合动力系统主要部件：发动机、ISG电机、发电机及动力电池等进行了选型和参数设计。并采用Cruise软件对原内燃机叉车和混合动力叉车的动力系统建模。分析并比较了并联混合动力汽车控制策略,在此基础上提出了混合动力叉车用电力辅助控制策略,在Simulink/Stateflow中建立了叉车混合动力系统控制策略模型。通过Matlab-DLL模块将所建控制策略模型导入动力系统模型后进行仿真,并对原内燃叉车和混合动力叉车在动力性能、经济性能方面进行分析、比较。仿真结果表明,本文所设计的混合动力叉车与传统内燃叉车动力性基本相当,且有明显的节能效果。本论文为混合动力叉车的进一步开发提供了理论指导和借鉴。
[Abstract]:Facing the great challenge of global energy crisis and environmental pollution, the development of new energy vehicles and construction machinery, the realization of energy saving and emission reduction of vehicles and construction machinery, and the promotion of strategic transformation of traditional industries have formed a broad consensus in the world. In recent years, with the development of economy and urbanization, construction machinery industry has been developing rapidly. Construction machinery is faced with the pressure of energy conservation and emission reduction increasingly severe. The traditional diesel forklift truck is widely used in construction machinery, its operating conditions and loads vary greatly and frequently. It is of great significance to use hybrid power system to save energy and reduce emissions of forklift. In this paper, 3 ton hybrid forklift truck is taken as the research object. Firstly, based on the overall analysis of the operating conditions of forklift trucks, the simplified operating conditions and operating characteristics of forklift trucks are proposed. Then, the configuration characteristics of hybrid electric vehicle are analyzed and compared, and the hybrid power configuration scheme of single axle parallel forklift truck is put forward. The main components of forklift hybrid power system, such as engine, ISG motor, generator and power battery, are selected and parameters are designed. Cruise software is used to model the power system of the forklift truck and hybrid electric forklift truck. The control strategy of parallel hybrid electric vehicle (HHV) is analyzed and compared. On the basis of this, the electric auxiliary control strategy for hybrid electric forklift truck is put forward, and the control strategy model of hybrid power system of forklift truck is established in Simulink/Stateflow. The control strategy model is introduced into the power system model by Matlab-DLL module, and the power performance and economic performance of the original internal combustion forklift and hybrid electric forklift are analyzed and compared. The simulation results show that the hybrid forklift designed in this paper has the same power performance as the traditional internal combustion forklift and has obvious energy saving effect. This paper provides theoretical guidance and reference for the further development of hybrid electric forklift truck.
