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 foroverhead contact line equipment inYingtan-Xiamen railway, and the current commonly-used compensation algorithmfor staggers, a newalgorithmwhich 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 resultswith a tolerance less than 30 mm amount to 80% in the total line.
