Research on the transmission loss of the floor aluminum profile for the high-speed train based on FE-SEA hybrid method

Firstly, FEM (Finite Element model) of the aluminum profile is built. The structural material parameters are then given to compute the free modals. After the comparison with the experimental results, the relative error of the modal frequency can be controlled within 5 %, which meets the requirements...
