차량(Rexton sports khan)의 주행 중 실내압력 변화에 대한 실험적 연구

초록

Recently, as the demand for electric vehicles increases, many improvements have been made to prevent noise from entering the vehicle interior. However, the perspective on the change in indoor pressure has been excluded. In this paper, the standard for the change in indoor pressure that can cause discomfort to the human body was set, and the change in indoor pressure that occurs during vehicle driving was measured. The Extractor Grille area was increased by 20 ㎠ and tested from 0 ㎠ to 200 ㎠. For each Extractor Grille area, the driving speed was increased by 20 km/h and the indoor pressure difference that occurred during driving from 60 km/h to 180 km/h was calculated. Through this experiment, we experimentally discovered that the Extractor Grille area has a significant impact on the indoor pressure generated during driving, and that the indoor pressure generated during driving can cause discomfort to the driver's body.
