IMPROVEMENTS OF MAINTENANCE CRITERIA COVERING THE RUNNING GEAR OF SHIN-KANSEN RAILCARS BY MEASURING THE TRANSVERSAL ACCELERATIONS OF THE BODY

SHIN-KANSEN DENSHA SOKO KANRI SHIRYO SEIDO UO KOJO NI KANSURU KENKYU

Osaka engine shed officials measure, under 200 km/h on line conditions, the body accelerations of Shin-Kansen railcars each time the wheels are re-profiled (every 70,000 km). Following these measurements, an index is calculated in accordance with an empirical formula that is a linear combination of the acceleration occurrence frequencies classified by section (linear combination of the values of the acceleration distribution analysis). Bogie overhaul is scheduled in accordance with the value of this index. In applying this method, the JNR encountered difficulties due to the effect of 3 factors on transversal accelerations: the state of the track, the speed (the index is very sensitive to speed variations of only a few km/h), weather conditions (transversal stability is distinctly improved in rainy weather). The article describes how corrective laws were worked out to eliminate the effect of the first 2 factors. For the 3rd factor, it was decided to limit measurements to periods of wet weather.
