| Abstract: |
| It was very important to establish a reasonable vehicle model to research the vehicle-bridge interaction.In order to reflect the dynamic response of bridge in vehicle loads,this paper based on LS-DYNA program,combined with the structural characteristics and parameters of heavy vehicle,simulated rubber tires,tire gas pressure,wheel rotation and suspension system to make the vehicle model more realistic.The validity of the vehicle finite element model was preliminarily verified by vehicle axle load and vehicle dynamic characteristics.Meanwhile,a simply supported hollow concrete slab girder bridge was taken as an example to verify the wheel rotation and vehicle-bridge interaction.The validity of the vehicle finite element model was further verified by comparing the LS-DYNA results with the measured results.They show that the three-dimensional vehicle finite element model based on LS-DYNA is feasible and can be used to study vehicle-bridge interaction. |
