The vibration of first vertical bending mode of railway vehicle body greatly affects the riding comfort for passengers. In recent studies of authors, it is estimated that the arrangement of underfloor equipment with large mass and stiffness influences the dynamic characteristic of railway vehicle. Therefore, the purpose of this study is to optimize the arrangement of underfloor equipment to achieve the low vibration design of railway vehicle. The optimum design problem involves discrete design variables and a new response surface methodology, based on holographic neural network, is developed in this application. The sequential procedure and the stopping criteria are proposed. As the optimization result, the optimal position of the underfloor equipment makes the first bending frequency largest and it is confirmed that the first body bending vibration is reduced.
