摘　　要：建立了纯电动拖拉机数学模型,考虑了滑转率、驱动电机实时工作效率。在动力电池组、驱动电机、作业条件确定的情况下,研究了使用质量、变速器速比、牵引负荷、载荷分配系数4个关键参数对纯电动拖拉机的续航能力的影响。结果表明,各参数对续航能力影响的敏感度依次为:载荷分配系数>牵引负荷>使用质量>变速器速比。续航时间随载荷分配系数的增大而增大,随牵引负荷的增大而减小。当载荷分配系数、牵引负荷一定时,绘制了续航时间随使用质量和变速器速比变化的三参数变化关系图。该研究成果,可为纯电动拖拉机的参数匹配提供技术支持。A mathematical model was established for pure electric tractors,in which the slip ratio and the real-time working efficiency of the drive motor were considered.In the case of known power battery,drive motor and working conditions,the influence of four key parameters(mass,transmission ratio,traction load and load distribution coefficient)on the endurance of pure electric tractors was studied.The results showed that the sensitivity of each parameter to the endurance capacity was load distribution coefficient>traction load>mass>transmission ratio.The endurance time increased when the load distribution coefficient increased and decreased when the traction load increased.When the load distribution coefficient and the traction load were constants,the graph of the endurance time varying with the used mass and transmission ratio was plotted.The research results can provide technical support for parameter matching of pure electric tractors.
