摘　　要：地铁列车控制优化与纵断面设计关系密切,二者对运营费用有重要影响。为在列车控制优化的基础上进一步降低运营费用,在线路纵断面设计阶段构建了协同优化模型,考虑定时列车控制对纵断面进行优化,在满足定时列车控制约束、《地铁设计规范》要求等的前提下,最小化能耗成本和维修成本之和。由于车轮、钢轨维修成本的影响因素众多,建立列车-轨道动力学仿真模型计算维修成本,在此基础上设计综合伪谱法和蛮力搜索的算法求解协同优化方案,并应用于广州地铁线路的3个区间,对方法的优化效果进行验证。研究结果表明,对比在实际纵断面上单独优化定时列车控制的方法,同时优化定时列车控制方案和纵断面方案对节约运营费用的效果更佳,各区间运营费用平均降低21%。该研究方法可为进一步控制运营费用提供新思路和理论依据,推动地铁系统可持续发展。Energy-saving metro train control is closely related to the vertical track alignment(VTA)design,and both have a significant impact on operating costs.To further reduce operating costs based on optimized train control,this study proposed a collaborative optimization model for the VTA design phase.This model optimizes the bidirectional train control strategy and VTA of a metro section with the goal of minimizing energy consumption and maintenance costs simultaneously,while adhering to the constraints of scheduled train control and the requirements of the"Metro Design Code."Given the numerous factors affecting the maintenance costs of wheels and rails,a train-track dynamic simulation model was developed to calculate these costs.Based on this,an algorithm combining the pseudospectral method and brute force search was designed to solve the collaborative optimization model.The effectiveness of this optimization method was validated using three sections of the Guangzhou metro line.The results indicate that,compared to the method of optimizing scheduled train control alone on the actual VTA,the collaborative optimization model is more effective in saving operating costs,reducing the average operating costs by 21%across the studied sections.This study can provide novel approaches and theoretical support to further reduce metro operating costs,which contributes to promoting sustainable development of metro.
