总量一致的机车牵引力优化分配方法
|
摘要
针对机车在正常运行过程中某轴电机由于故障导致该轴牵引力发生损失的情况,提出总量一致的机车牵引力优化分配方法。以四轴机车为例,考虑轴重转移对各轴牵引力的影响,给出了牵引总量一致性的关系表达式,构造了关于总轴重转移量的优化目标函数,并利用遗传算法得到了该目标函数值最小情况下的最优牵引力。
In view of the loss of traction of a certain axis motor due to its failure in the normal operation of a locomotive, a method of optimal distribution of locomotive traction has thus been proposed. Taking a fouraxle locomotive as an example, with the effect of axle weight transfer on the traction force of each axle taken into consideration, the relationship expression of the total traction amount can be worked out, thus constructing the optimal objective function of the total axle weight transfer amount, and obtaining the optimal traction force with the minimum value of the objective function by using the genetic algorithm.
