A time-domain stepwise fatigue assessment to bridge small-scale fracture mechanics with large-scale system dynamics for high-speed maglev lightweight bogies
Abstract
Maglev trains with an operation speed higher than 600 km/h show a great advantage during the next generation ground transportation. To tackle the structural integrity of maglev bogies made of forged 6082-T6 aluminum alloys, a time-domain stepwise fatigue assessment (TSFA) approach was proposed to consider complex dynamic fatigue loads. Firstly, a vehicle-bridge coupled maglev vehicle dynamic model was established to obtain the time history of...
