A method for judging idling of a train wheel set comprises the following steps of: calculating an idling risk value by adopting a nonlinear mathematical model according to a creeping degree change rate, creeping degree and a train wheel set speed change rate, and integrating a plurality of single threshold value judgment conditions of traditional wheel set idling and weighted judgment conditions under the condition that the single threshold value conditions are not met into a whole. According to the method, the judgment basis is simplified, weighting calculation is carried out after multiple factors are quantized under the condition that single threshold conditions are not met, multi-factor comprehensive judgment is achieved, and idling judgment is more comprehensive and accurate. Through selection of a nonlinear mathematical model, the possibility of misjudgment of weighted judgment conditions under the condition that single threshold conditions are not met can be avoided as much as possible, and idling judgment and idling traction control are more comprehensive and accurate.

    一种列车轮对空转判断方法,依据蠕滑度变化率、蠕滑度和列车轮对速度变化率,采用非线性数学模型计算空转风险值,将传统轮对空转的多个单项阈值判断条件与单项阈值条件均不满足的情况下的加权判断条件综合为一个整体,简化了判断依据,也在单项阈值条件均不满足的情况下,将多个因素量化后进行加权计算,实现多因素的综合判断,使空转判断更为全面准确。非线性数学模型的选取,能够尽量避免单项阈值条件均不满足的情况下加权判断条件的误判可能性,使空转判断和空转牵引力控制更为全面准确。
