함상탑재용 페데스탈의 해상 진동환경 내 진동안전성 분석

Equipment mounted naval vessel is exposed to a diversity of environments such as the wind and waves, warship engines, propeller driving forces. In the event that the energy of the wind and waves are continuously transmitted to the warship housing happens to be led the deterioration in performance of the onboard equipment and mechanical damage. It should be considered in the design phase that the shock absorbing and vibration control with respect to the vertical direction in the system since the pedestal have an directivity while operation. Therefore in this study it is confirmed that the structure of the pedestal is designed robustly against a disturbance by performing structural analysis and tests in the random vibration conditions and system frequency design with a spring constant of the shock absorber.
