跨坐式单轨列车牵引电算模型研究

Computer Model of Straddle-type Monorail Train Traction

列车的牵引计算是轨道交通研究的重要组成部分。由于跨坐式单轨列车结构特殊,其牵引计算模型与普通轨道交通列车差异较大,通过分析跨坐式单轨列车的牵引特性,选择优化控制牵引策略,建立单轨列车启动过程、牵引过程、惰性过程、制动和进站过程计算模型。以运营中的重庆轻轨2号线为试验线路,实现整个列车运行过程模拟。计算结果表明,计算模型正确,能使列车准确停靠站台,具有一定实用价值。

The traction calculation of rail vehicle is an important part of the whole rail system. Due to the special structure of straddle-type monorail car, its calcution mode is quite different from the common rail vehicles. Through an analysis of the traction characteristics of straddle - type monorail car, this paper adopts the optimal control traction strategies to establish a traction calculation mode,including traction process, inert process, brake and the end of process. By taking light rail Line 2 of Chongqing City as the experiment line, the entire train movement process simulation is completed and the results show that the traction calculation model is correct, it can stop the train at platform accurately and therefore has some practical value.
