船舶区域舱室复合环境综合评价方法研究

舱室环境直接影响船舶居住性和船员舒适性,可以此为切入点通过环境评价来验证布置方案的合理性。该文通过对舱室温度、光照、通风和噪声的分析,明确了舱室环境因子的影响原则,并在此基础上引入模糊数学理论,建立综合评价数学模型并进行验证。结果表明:模糊综合评价方法能较好反映区域舱室复合环境状况的好坏,为舱室布置提供客观的数据支撑。

船用玻璃纤维增强复合材料与钢连接结构的力学特性（英文）

The use of a glass-fiber reinforced composite in marine structures is becoming more common, particularly due to the potential weight savings. The mechanical response of the joint between a glass-fiber reinforced polymer(GRP) superstructure and a steel hull formed is examined and subsequently modified to improve performance through a combined program of modeling and testing. A finite-element model is developed to predict the response of the joint. The model takes into account the contact at the interface between different materials, progressive damage, large deformation theory, and a non-linear stress-strain relationship. To predict the progressive failure, the analysis combines Hashin failure criteria and maximum stress failure criteria. The results show stress response has a great influence on the strength and bearing of the joint. The Balsawood-steel interface is proved to be critical to the mechanical behavior of the joint. Good agreement between experimental results and numerical predictions is observed.
