| 摘 要： | 该文阐述了键合图理论的基本原理,并根据电动汽车纵向运动时传动系统各单元的动态特性及其相互作用的工作原理和结构特点,运用键合图理论构建出电动汽车电机驱动系统的键合图模型,并推导出该系统的状态方程,应用Matlab仿真软件对建立的数学模型进行仿真分析.仿真结果表明:键合图法是一种对系统进行动态数字仿真时有效的建模工具,应用该理论对系统进行仿真能较好地反映系统的动态特性和整车性能,并可以利用仿真结果来检验动力系统的参数选择是否合理,以此作为对参数进行修改的依据.

| Abstract: | The fundamental principle of bond graph theory was stated in this paper, and then the theory was applied to design a complete bond model of electric vehicle motor powertrain system according to the analysis on dynamical performance and interaction of each unit in the power train system for electric vehicle, and the state equations of system were established. Finally the bond model was simulated by Matlab software. The simulation result shows that the bond graph is a valid method to integrate both bond graph theory and SIMULINK simulation into system dynamics analysis can be applied to dynamics modeling and analysis of vehicle power transmission. |
