基于遗传算法的铁路平车锁座调整方案研究

Method for Adjusting Lock Brackets of Flat Cars Based on Genetic Algorithm

针对铁路集装箱运输过程中,由于铁路平车锁座平面度超差而导致集装箱倾覆等现象,制定了锁座高度调整方案.提出以遗传算法基本模型为基础,建立相应的平车锁座调整算法模型.应用遗传算法中的种群自然选择原则,确定锁座调整过程中基因变量和染色体变量,并根据选择过程中的约束条件要求,定义适应度函数,进行多代筛选.最终得到调整锁座数最少且调整总高度值最少的最佳高度调整方案.

Aiming at the unqualified flat cars with oversized flatness,a new method is proposed to make ad- justment schemes based on genetic algorithm model. According to natural selection principle, related parame-ters are defined as gene and chromosome as well as fitness function. Through multiple iteration, the best ad-justment scheme can be determined.
