Analysis of Dynamic Response of Subway Train Under-crossing High Speed Railway
Based on the platform of ABAQUS software, a 2D elastoplastic multi-vibration calculating model which is simulating subway train under-passing high speed railway is established, using the combination of finite element method and infinite element method. Vertical vibrating load induced by high speed train and subway train are simulated with excitation function and are imported by multi-point input method. The fundamental frequency and damping of the vibrating system are simulated. The acceleration, stress of measuring points caused by different vibrating load are calculated, the interaction between two kinds of loads and the regular pattern of dynamic response are studied.
