摘要
针对当前工程设计环节中电气化复线铁路轨道电路横向连接位置计算完全依靠人工、计算工作量大且准确性不高的情况,在充分考虑模型准确性、设计规范、工程预算、牵引回流性能等因素的前提下,提出一种多线引入情况下的电气化复线铁路轨道电路横向连接位置优化计算方法。首先,构建多线引入情况下的横向连接位置数学模型,并进一步将横线连接位置的工程计算问题描述为多目标数学优化问题,建立横向连接位置优化问题的数学模型;然后,在分析各目标函数间特性的基础上,提出一种基于多目标粒子群的横向连接位置优化计算方法;最后,采用实际工程数据对算法进行验证。计算结果表明,算法能准确对横向连接位置进行计算,并大幅提升横向连接工程设计效率。
In view of the fact that the location calculation of track circuit transverse connection in double-track electrified railway is completely manual with great calculation workload and inaccuracy under current engineering design process,an optimized location calculation method for track circuit transverse connection in double-track electrified railway is proposed,fully considering the model accuracy,designing standard,project budget,traction return performance and other factors.Firstly,a mathematical model of transverse connection location considering multi-line introduced is constructed.Furthermore,this engineering calculation problem is described as a multi-objective optimization problem and a transverse connection location optimizing model is established.Secondly,on the basis of analyzing the characteristics of each objective function,a method for optimizing the track circuit transverse connection location is proposed based on multi-objective particle swarm optimization(MOPSO).At last,the algorithm is verified based on actual engineering data,and the results show that it can accurately calculate the transverse location and greatly improve the efficiency of transverse connection location engineering design.
