The use of accelerometers in pantograph testing
The article describes advanced methods for testing electric rolling stock pantographs, based on the use of accelerometers. The methods allow improving accuracy and reliability of measurements, reducing complexity of testing procedure and increasing informativity of the recorded parameters. The use of small accelerometers allows to equip any type of pantograph with measurement system without making changes to its design and performance characteristics, and, therefore, carry out tests in laboratory and on existing lines more efficiently and with less efforts.
