摘　　要：针对直线感应电机(LIM)在轨道交通领域采用不同材料反应板的情况,在提出牵引力准则的基础上,计算了采用铜、铝2种反应板的直线电机在启动加速阶段的能耗情况。计算表明,在低速阶段铜导电板电机的功耗低于铝导电板电机的功耗,在高速阶段情况则相反。因此综合能耗和建造成本等因素,可以考虑在轨道的不同区段采用不同的反应板材料。As different materials are used for the reaction plate of linear induction motors（LIM） in railway transport, it is calculated the energy consumption of the LIM with copper and aluminum reaction plates at the acceleration stage, based on the proposal of traction effort criteria. The calculations show that the energy consumption of LIM with copper reaction plate at low speed range is better than that of LIM with aluminum one, while at high speed range, it is worse. Therefore, after synthetic consideration of energy consumption and construction cost, it is proposed to use different reaction plate materials in different sections of the railways.
