School of Electrical Engineering, Southwest Jiaotong University, Chengdu 611756, China

摘要

摘要:
为分析接触网承力索静止与振动状态下的线索形状与集中荷载对应关系. 采用抛物线法对静止状态的承力索进行找形计算，通过构建振动微分方程和使用傅里叶变换计算振动状态下的承力索形状；结合受力分析，并根据牛顿第二定律推导静止与振动状态下承力索集中荷载的公式，在获取静态与振动状态下集中荷载处位移变化后，可以通过该公式求解集中荷载；在实验室搭建的振动试验台上对测量方法进行了检验. 检验结果表明：静态时的绝对误差为0.20%，主振频率为1 Hz及2 Hz振动状态下的绝对误差百分比均在0.50%以内；采用机器视觉获取集中荷载处静态位置与振动位移数据，进而实现承力索集中荷载非接触测量的方法是可行的.

Abstract:
Relationship is explored between the wire shape and concentrated load of catenary messenger wires in static and vibrational states. The parabola method is used to determine the messenger wire shape in static state. By constructing the differential equation and using the Fourier transform, the messenger wire shape in vibrational state is calculated. Combined with the force analysis, the concentrated load formula of the messenger wire in static and vibrational states is deduced according to Newton's second law. After acquiring the displacement at the concentrated load in static and vibration states, the concentrated load is solved, and its measurement method is tested on the vibration measurement platform built in lab. The test results show that the percentage of absolute error in static state is 0.20%, and in vibrational state with main vibration frequencies of 1 Hz and 2 Hz it is within 0.50%. It is feasible to use machine vision to obtain the static position and vibration displacement data at the concentrated load, and thus realize the contactless measurement for the concentrated load of messenger wires.
