LIFE PREDICTION OF METRO OBSTACLE DETECTOR BASED ON FATIGUE TEST AND FRACTURE SIMULATION
Using the vibration excitation spectrum of IEC61373, the subway bogie obstacle detector was taken as the research object. The random vibration fatigue strength of the obstacle detector was studied by combining the finite element method and bench vibration test, and the remaining life at the fatigue...
