- Title
Effects of the range and frequency of vibrations on the momentary riding comfort evaluation of a railway vehicle.

- Abstract
When trains pass level-crossings, turnouts, and rail joints, they are momentarily subjected to extreme vibrations. In railway engineering, evaluation of the riding comfort under such occasional vibrations is called the momentary riding comfort evaluation, as distinct from the long-term evaluation, which addresses the riding comfort of passengers for certain lengths of train operation. In order to identify the effective vibrational characteristics of the momentary evaluation, an experiment was performed with a riding comfort simulator. Ten adult subjects for each condition, 80 in total, participated in the experiment. The effects of differences in the range of stimuli, frequency of each stimulus, and scores on a rating scale of discomfort were studied. Differences in the range and frequency affected the evaluation such that subjects tended to make a relative judgment on discomfort. They made almost an absolute judgment when the rating scale was well defined, with a small number of categories.
