바지선의 예인안정성에 관한 수치해석 연구

다국어 초록 (Multilingual Abstract)

This paper presents a numerical study on towing stability of barges. Towing simulations are carried out by using two different numerical models(MMG model and Cross-Flow model). Stability criteria are also suggested based on the analysis of the linearized governing equations for towed vased motion. In order to validate present nurreical model,s experimental data of Yasukwa et al.(2006) are used Single and double barges are simulated under the constant towing speed and direction conditions. Time histories of heading angle yaw rate and towline tension are compared between numerical results and experiments. The effects of towline length on slewing frequency and maximum heading angle are also observed. Though these calculation,s applicability of two numerical models in towing, stability analysis are studied.
