정량화 평가 방법에 의한 트럭의 승차감 연구

We need the target of vibration characteristic to improve ride performance of running vehicles. This target is different between humans as their sensitivities for vibrations, motions of vehicle and to get this target has been depended on experimental test drivers. They have been studied in human dynamic characteristics, sensitivity with multiple axis vibrations as well as single axis vibrations. But it is difficult to determine assessment criterion of ride comfort. Because subjective rating of ride comfort is different among people, in'dividual feel ing, age, sex etc. In this study, we find relationship between measuring values of vehicle vibration characteristic on each test road and subjective rating of ride comfort by correlation analysis, and predict total subjective ride comfort value of vehicle by multiple regression equations.
