Abstract

The final goal of this research is to establish the relative dangerousness D/B for factors on seakeeping performance. This D/B is essential to develope the seakeeping performance evaluation system built-on-ship. The system is composed of the apparatus for measuring a vertical acceleration to be generated by the ship's motions, computer for calculating the synthetic seakeeping performance index and monitor for displaying the evaluating diagram of navigational safety of ship. In this paper, a methodology on the establishment of the relative dangerousness D/B for factors on seakeeping performance is presented by a numerical simulations, playing an important role on the algorithm of the program for calculating the synthetic seakeeping performance index. Finally, It is investigated whether the relative dangerousness D/B can be realized an accurate values according to the loading conditions, weather conditions, wave directions end present ship's speed of a model ship.

LMTT(Linear Motor-based Transfer Technology)는 항만 자동화를 위한 컨테이너 터미널용 수평 이송 장치이며, rail과 shuttle car(mover)에 부착된 stator module로 구성된 PMLSM(Permanent Magnetic Linear Synchronous Motor)에 의해 구동된다. 본 논문은 inner beam과 outer beam의 높이비가 LMTT용 shuttle car의 frame 강도 및 강성에 미치는 영향을 살펴보았다. 설계변수는 inner beam의 단면형상 및 높이비로 설정하였으며, 유한요소해석을 통하여 설계변수가 frame의 강도 및 강성에 미치는 영향을 살펴보았다.
