Measuring device for measurement of train dynamic motion during wheel slip

摘要

For a locomotive wheel slip velocity detection and slip control are typically used measurement sensors that are mounted on the locomotive. The sensors are typically intended for another purpose e.g. wheel speed measurement or tractive effort determination. When the slip control is based on indirect methods that needed to measure some specific locomotive behavior that occurs during high slip velocity it is difficult to use the locomotive measurement sensors. The paper presents an additional experimental measurement device that is mounted on locomotive wheelset to measure the wheelset dynamic motions that typically occur when the wheel has large value of slip velocity. The measurement device is equipped with accelerometers. Measured data are filtered to get signal that can be used for locomotive wheel slip velocity detection and control.
