鉄道乗り心地評価のための評価グリッド法実験の提案

抄録

The evaluation grid method is a method that aims to extract the cognitive structure, which is a mechanism of understanding and judgment unique to each person. In general, the evaluation grid method uses about 30 photographs as elements (objects to be investigated). However, in the evaluation of ride comfort, subjects need to memorize the vibration conditions for each different sensory condition. Therefore, in order to facilitate the ranking of the sensory evaluation when answering the questionnaire, the number of vibration conditions in one test condition was set to three, and four types of experiments were conducted to extract the evaluation structure in railroad ride comfort and to show the effect of this structure.
