Developing a quiet car requires minimizing the vibration of the floor panel. In this study, the objective of the floor panel design is to obtain the high stiffness by introducing the curved surface panel. The finite element model of both bead and curved surface panel was first built. Next, the structural vibration was conducted. And, the different floor panel designs with curved surface were evaluated. In result, the floor panel design with curved surface showed a significant high stiffness in the desired frequency range
