The fatigue analysis on the hanger of the under frame equipment of the EMU
The random vibration excitation of the hanger is the main cause of its fatigue failure.According to the random vibration excitation of rail vehicles given by the IEC 61373 standard,and combining with the finite ele-ment model of the hanger,the random vibration theory and fatigue analysis theory,the random vibration fatigue life simulation analysis under frame equipment hanger is carried out to explore the change law of the fatigue dam-age of different hanging frequencies.The experiment is carried out when the suspended frequency is 8 Hz,which verifies the reliability of the simulation results.
