为提高高速铁路运行节能降耗效果,在优化线路纵断面的设计中引入节能坡设计是有效途径之一。然而由于高速铁路具有行车速度高、区间距离长、曲线半径大等特殊性,使得节能坡设计应用变得极为复杂。在对列车节能运行操纵优化问题数学描述的基础上,针对列车节能操纵优化问题数学模型非线性、有约束的最优化特性,提出工况序列表与基于改进实数编码遗传算法相结合的高速铁路区间节能坡设计方法,解决节能坡在高速铁路区间的设计应用问题。实验结果表明:该方法能够在最大范围和最大程度上寻找最优设计结果,较好地满足区间节能坡设计。
In order to improve the energy saving effect of high-speed railway operation, it is an effective way to introduce the design of energy-saving slope into the design of the optimized line profile. However, due to the special features of high-speed railway such as high speed, long range distance and large radius of curve, the application of energy-saving slope design becomes extremely complicated. Based on the mathematical description of train operation optimization problem, aiming at the non-linear and constrained optimization characteristics of mathematical model of train energy-saving operation optimization problem, this paper presents a combination of working sequence table and high-speed railway based on improved real-coded genetic algorithm Energy-saving slope design method to solve the design and application of energy-saving slope in the high-speed railway. The experimental results show that this method can find the optimal design results in the largest range and maximum extent, and meets the design of energy-saving slope in the interval.
