Abstract
A contact force between pantograph and contact line is one of the important
criteria to evaluate contact performance. Hence, contact force measuring
methods were developed. The currently-used measurement methods use built-in
sensors on the panhead. However, these sensors affected the dynamic
characteristics of the pantograph. In addition, the methods need data transmitting
equipment, because built-in sensors are set under a high-voltage condition. To
eliminate these drawbacks, the authors have developed a new contact force
measuring method which can replace the all built-in sensors with image
processing sensors mounted on the rooftop of the train. To verify measurement
accuracy of this method, we performed an excitation test of the pantograph.
Experimental results show that the measurement method meets the requirements
of the EN standard.
