Recently, aluminum alloy double skin structures are utilized for car bodies of high-speed railway vehicles such as Shinkansen trains to reduce weight of railway vehicles. However, radiated sound power level of the structure tends to be high at 800 Hz. This characteristic was improved by installing damping materials on the structures. For further improvement, qualitative discussion on dynamics of the structure is required. In this study, the authors derive kinematic equations by using Finite Element Method (FEM) and carry out numerical simulations. The comparison of the simulation results with the experimental results shows that the proposed method to derive the kinematic equations is valid.
