摘要
地铁线路限界设计是保证地铁车辆安全运行的关键技术。合理精确的限界设计可以减少土建投资,节约成本。其中,相对于直线地段,曲线地段的限界加宽量计算相对复杂,方法也不尽相同。通过分析地铁车辆在圆曲线、缓和曲线以及曲线过渡段的限界加宽量,利用MATLAB编写相应的程序,进一步简化地铁线路曲线地段限界的计算。
Gauge is the key technology to ensuring the safe operation of metro vehicles.In addition,reasonable and accurate gauge can reduce the investment.Compared to a straight-line section,the calculation of the gauge widening in a curved section is relatively complicated,and the methods are different.By analyzing the clearance widening of a metro vehicle in a circular curve and transition curve,a corresponding program was made using MATLAB to simplify gauge calculation.
