| 摘 要： | 在分析电动汽车动力学模型和永磁直流电动机数学模型的基础上,建立了永磁直流电动机驱动汽车的数学模型;考虑到电动机通用数学模型的普适性,决定采用其主要参数和环节,并辅以相应的非线性环节构建了电动机驱动汽车的动态结构图,推导出转动惯量和机电时间常数的计算公式。研究结果表明:该模型更好地反映了电动汽车运动受风阻影响这一特殊性;推导出的计算公式能够实现机(汽车)电(电动机)系统的有机结合,使各参数的物理意义更加明确。

| Abstract: | Based on analysis for dynamic model of electric vehicle and mathematical model of permanent magnet DC motor,the dynamic mathematical model for electric vehicles driven by permanent magnet DC motor was established.In consideration of the universality of general mathematical model of motor,the dynamic block structure diagram for electric vehicles driven by DC motor was constructed by using its main parameters and links as well as some auxiliary non-linear links.Calculated formulas for rotational inertia and e... |
