摘　　要：分析了在高速动车组制动系统中增加线性涡流制动后,涡流制动力和空气制动力的分配原则。接着讨论了基于试验数据建立钢轨温升和闸片磨耗数学模型的方法。基于经验公式以减少钢轨温升和减少闸片磨耗为目标,提出一种分配涡流制动力和空气制动力的优化控制策略。通过优化计算,给出了涡流制动力和空气制动力的分配关系。Blending principle between eddy current brake force and Pneumatic brake force was analyzed after linear eddy current brake mode was added in brake system of high speed EMU. The model creation method of temperature growth of the rail and abrasion of disc pad was discussed. Based on empirical formula, in order to reduce temperature growth of the rail and abrasion of disc pad, an optimiza- tion strategy of distribution between eddy current brake force and pneumatic brake force was presented. Through optimization computation, the distribution relation between eddy current brake force and pneumatic brake force was provided.
