这项研究开发了一个时间驱动的火车性能模拟（TPS）模型，该模型由火车牵引模块，轨道对准模块和火车控制模块组成，该模型用于模拟火车的移动，计算能源消耗和估计旅行时间，考虑到考虑时间在本研究中给出了各种垂直轨道比对和操作控制。拖流努力，阻力，加速度，速度和能耗等）并计算能源消耗和旅行时间。确定了依从性，而海岸位置对旅行时间和能源消耗的影响也进行了评估。讨论了控制变量。
This study develops a time-driven train performance simulation (TPS) model consisting of train traction module, track alignment module, and train control module, which is applied to emulate the movement of a train, calculate energy consumption, and estimate travel time, considering various vertical track alignments and operational controls. A numerical example is given in this study to demonstrate the features of the developed TPS, such as generating time varying operational measures (e.g., the tractive effort, resistance, acceleration rate, speed, and energy consumption, etc.) and calculating energy consumption and travel time. The most energy efficient train control, or called “golden run,” associated with various track alignments, speed limits, and schedule adherence are identified, while the impact of coasting locations to travel time and energy consumption is also assessed. A sensitivity analysis is conducted, and the relationship between model parameters and control variables are discussed.
