连续复合曲线段接触网精确测量计算研究和应用

Studies and Application of Accurate Measurement and Calculation of OCS at Continuous Composite Curve Section

铁路线路部分曲线区段条件复杂,连续复合曲线给接触悬挂承力索安装带来较大难度,同时接触网关节及电分相区段的接触网参数调整存在导高非自然抬升和两支接触悬挂间距问题,给吊弦测量及计算带来更大难度。本文通过分析轨面与接触悬挂的模型,计算得出相应的数学关系,并针对接触悬挂安装、吊弦数据采集、吊弦数据处理、吊弦计算等全过程,研究了有砟常动轨铁路接触网吊弦数据处理及计算施工技术,该施工技术可有效满足稳定的弓网关系对定位装置参数的要求。

The complicated conditions of part of curve sections of railway line bring rather difficulties to the installation of messenger wires of overhead contact line at continuous composite curve section,at meanwhile,there are problems of unnatural uplift of contact wire and spacing between two contact lines for OCS parameter modification at overlap section and phase separation section,resulting in more difficulties for measurement and calculation of droppers.The paper,by analyzing of models of rail top and contact line,calculates and obtains the related mathematical relations,studies the construction technology for OCS dropper data processing and calculation for ballast mobile track,this construction technology is able to meet the requirements of stable pantograph-catenary interactions on the parameters of registration devices.
