The Fatigue Life Evaluation and Load History Measurement of Motor Block Bracket Unit for KTX-Sancheon Trains

초록

In this study, design fatigue life of the motor block bracket units for KTX-Sancheon trains were assessed. Evaluation method the welding department fatigue strength relation strain gauge establishment location and method of the railway car structural body led and ERRI B 12/RP 60 they executed. The actual vehicle dynamic stress test which is applied from the research which sees from KTX-Sancheon trains service line executed with service operting speed. The railway vehicle dynamic stress measurement system used DAQ (MGC plus) systems which had become commercial business. The analysis applied BS 7608 - Class F about actual vehicle dynamic stress. Analytical result, when KTX-Sancheon trains annual 600,000km that travels, assuming, 30 in plan life travels the possibility is safe of knowing was very.
