Fatigue analysis of bogie tow bars on subway wagon.
Original language description
The metro wagon bogie tow bar consists of three main parts; the central tube part and two lugs. These parts are welded to each other. Metro tow bars cracks had appeared during the operation on the wagons near the welds. Metro operator assigned the examination of tow bars fatigue life. Strain gauges ware installed on the tow bar and the loading spectrum was measured during an operation. Two bars ware loaded by means of loading spectra and the initialization and propagation of crack was monitored. A measurement of the loading spectra of the metro wagon bogie tow bar showed high peaks in the operational loading, which can leads to the fatigue crack initialization.
