摘要
动车组仿真计算以车辆牵引特性、阻力、制动减速度等关键参数作为输入条件,根据线路情况和操作需求进行仿真计算,分析动车组运行过程中运行时分、行驶距离、能耗等指标。以往通过手动控制调速的仿真系统中,常常需要反复多次操作,存在控速不精准、仿真计算效率低的问题。文中分析了动车组各种预减速情况,利用目标距离模式曲线实现自动减速控制,并在仿真系统中进行验证。
EMU simulation system takes key parameters such as traction characteristics,resistance,braking deceleration and other pa⁃rameters as input conditions,then carries out simulaton calculation according to line conditions and operating requirements,finally ana⁃lyzes the runtime,distance,energy consumption during EMU operation.In the past,speed regulation of simulation system need operat⁃ed repeatedly by manual control which exsisted incaccurat and low efficieny problems.This article analyzes various pre-deceleration situa⁃tions,uses the target distance mode curve to achieve automatic deceleration control,and verifies the effectiveness.
