Development of the technology to reduce vibration and noise is essential to improve the riding comfort in trains. To set the targets for development, it would be useful to have an index for evaluating the riding comfort quantitatively from the viewpoint of passengers. In order to establish techniques to accurately estimate the riding comfort, therefore a new simulator has been developed. This test apparatus has a mock passenger room furnished with 12 seats mounted on a 6-axis motion base. Since vibration, noise, temperature and window visuals can independently be controlled, the simulator will contribute to identifying the influence of plural factors on passenger comfort.
