摘要
针对目前没有形成有轨电车结构和模块编组特点的限界计算方法的现状,提出有轨电车动态限界(水平限界)算法。该算法基于解析几何方法,结合列车动力学分别推导出有轨电车在直线和曲线运行情况下以及有、无强侧向风情况下车体横向偏移量,计算出车辆动态限界。同时通过Matlab软件开发平台设计了有轨电车动态限界计算软件。该软件具有导入计算参数与导出计算结果的功能,通过软件计算,可以得到不同运行情况下有轨电车车辆横向限界值。最后给出计算实例来对算法进行验证,实验结果表明,该算法满足实践工程需求。该软件可供有轨电车车辆限界设计参考使用。
Because there is no calculation method of dynamic gauge for trams with its structure and module marshalling characteristics, this paper proposes a calculation method of dynamic gauge （horizontal gauge） for trams. Based on analytic geometry method and train dynamics, this algorithm derived the lateral offset of car-body when trams operated under different circumstances including in line and curve and with a strong side wind or without strong side wind, then the dynamic gauge of trams was calculated. At trams was developed through the Matlab software platform the same time, the dynamic gauge calculation software for This software has functions of import calculation parameters and export calculation results. Through this software, the lateral gauge values of trams under different situations can be calculated. Experimental results show that this calculation method can meet the needs of practical engineering. Therefore this software can be used as references in vehicle gauge design for trams.
