FRP遊艇於船架支撐下之變形分析

The Investigation on the Deformation Analysis of the FRP Yacht Supported by the Cradles
作者 李雅榮賴佩岑鍾承憲曾祥達詹育提
中文摘要
遊艇在製造和搬運的過程中,須置放於船架上。因船架只支撐在局部位置,不均勻的船身自重和艤裝使得船身產生變形,造成船殼外部膠殼產生裂痕和內部裝潢產生破損,既不美觀又會影響商譽,更甚至導致結構破損而影響其安全性。本文探討複合材料遊艇,針對既有的船型及船架,建立實船變形之量測系統,紀錄實船於施工各階段船架上之變形情形,並依照實際尺寸、形狀和使用材料,建立全船有限元素模型進行結構分析,探討其結構之受力及變形情況。進而更改船架支撐位置,以減少在船架支撐下,船身重量造成之變形量以及因其引起之後續問題。 Cradles are always needed for supporting the yachts during their construction and transportation. Local concentrative forces loaded by the non-uniformly distributed weights of yacht itself are only applied on the certain contact area between hull and cradle brackets. The deformed FRP hull, cracked gel coat, the distorted furnished interior and joinery work all cost the builder a lot to repair the imperfections. Moreover, even in the worst condition, the safety issue occurs owing to the structure failing which might not be solved by money only. This paper aims to establish the deformed measurement system for the yachts. Combined with the information of existing cradle, such as dimension, material and the measured data, finite element model of a target boat including whole boat structures, for example, hull, bulkheads and stiffeners, etc, can be established. By using commercial FEA software ABAQUS, the response of the structure supported by cradles can be obtained, and compared with the measured data to validate. It would help the optimization of the design of hull and cradle and reduce the problems caused by deformation.
