列车振动下接触网拉出值补偿算法

依据鹰厦线接触网检测车现有拉出值和列车振动检测数据及计算方法，提出了一种基于ＢＰ网络的新算法实现拉出值补偿计算，为供电段有效利用检测车动态检测数据指导静态检修提供了依据。实验结果表明；与人工测量值比较，误差〈３０ｍｍ的可达８０％。

A Compensation Algorithm for the Staggers of Contact Network under Train Vibration

According to the present staggers and the data tested under train vibration by the inspection cars for overhead contact line equipment in Yingtan Xiamen railway, and the current commonly used compensation algorithm for staggers, a new algorithm which is based on the BP neural network is developed for compensating the staggers of overhead contact network under train vibration. It provides a basis for power supply sections to conduct static inspections by using dynamic inspection data obtained by inspection cars. Experimental results show that: compared with the manually measured data, the compensated results with a tolerance less than 30 mm amount to 80% in the total line.
