초록

이 논문에서는 프로토타입(prototype) 고충격력 기구에 대한 최적의 절연시스템이 연구된다. 이 목적을 위해 첫째, 고충격력 기구의 특정한 작동조건하에서 인체의 거동과 전달력이 고안된 시험 장치를 이용한 실험을 통해 분석된다. 최적 동흡진기를 설계하기 위하여, 파라미터 최적과정이 충격량과 전달력의 실험결과를 토대로 한 단순화된 절연시스템 모델을 사용하여 이루어진다. 최종적으로, 충격완화 변위와 전달력의 구속조건을 만족시키는 파라미터 하에서, 프로토타입 고충격력 기구에 대해 최적 설계된 절연시스템의 성능이 실험에 의해 평가된다.

In this study the optimal isolation system for the prototype HIFD(high impulsive force device) is investigated. For this purpose, firstly, the dynamic behavior of a human body and a transmitted force under specific operation conditions are analyzed through a series of experimental works using the devised test setup. In order to design the optimal dynamic absorbing system, the parameter optimization process is performed using the simplified isolation system model based on the experimental results of linear impulse and transmitted force. Finally, under the parameters satisfying the constraints of the buffering displacement and the transmitted force, the performance of the designed isolation system for the prototype HIFD is evaluated by experiment.
