摘　　要：根据动车组制动系统中减速度特性以及相关牵引制动计算和运动学理论,文中提出了一种平直道环境下基于不等距点分割与人工鱼群算法结合的制动计算方法,同时对动车组的制动近似算法产生的计算误差进行分析。首先,根据列车制动原理中相关计算参数来构建动车组制动距离和制动时间的数学模型。然后,利用人工鱼群算法的优化原理并结合不等距分割思想对所建立的动车组制动距离和时间模型进行有效制动计算。最后,通过文中方法所得计算结果与CRH6A型动车组制动系统的性能型式试验实测数据进行对比分析,验证了该方法的可行性和有效性。Aiming at the large error caused by the approximate braking algorithm of EMU and the complexity of the brake calculation integral method for solving the original function process,a braking calculation optimization method based on the combination of unequal distance point segmentation and artificial fish swarm algorithm in the straight road environment is proposed.Firstly,the mathematical models of brak⁃ing distance and braking time of EMU are constructed according to the relevant calculation parameters of train braking principle.Then,the braking distance and time model of EMU is calculated effectively by using the optimization principle of artificial fish swarm algorithm com⁃bined with the idea of unequal distance segmentation.Finally,the feasibility and validity of the method are verified by comparing the calculat⁃ed results with the test data of CRH6A EMU.
