A Study on the Flight-time Limitation at each Mission in Whole-Body Vibration Exposure of UH-1 Pilot
UH-1H 조종사의 전신진동 노출에 따른 임무별 비행시간 한계에 관한 연구
Abstract
Vibrations exposured to human whole-body are transmitted through the contact area of a human body, such as feet, hip and back directly in contact with vibrating surface. they apparently leads to the decrease of human comfort, the reduction of working efficiency or normal activities, and, furthermore, causes the loss of health and safety. In this study, UH-1 vibration has been measured to produce the flight-time limitation at each mission Results of this study show that the most significant peaks appear at a main rotor blade-passage frequency and that the vibration level in ground is higher than that in airborne In addition, it is shown that the most affective aspect for the flight-time limitation is ground vibration level
