Mobile observation platforms are widely used in oceanographic and marine resource exploration and other applications. Wave Glider is a mobile platform that can transform wave energy into locomotion power and overcome the bottleneck of low energy supply. Wave Glider has recently been applied to tow underwater sensors fulfilling observation tasks. In this paper, the dynamic system of Wave Glider with a towed body is studied by applying multibody mechanics, and the relevant motion conditions of the system are investigated. Dynamic models of Wave Glider with a towed body and tether are first developed individually and then integrated into a whole model. The numerical method is used to obtain the dynamic responses and assess performance of the towed body pulled by the submerged glider of Wave Glider. The effects of sea state, mass of the towed body, and length of the towed cable are investigated on the basis of simulation results. This work can be used for the design and analysis of Wave Glider-towed body systems.  相似文献

Evaluation and classification of seawater corrosiveness by environmental factors     

朱相荣  黄桂桥 《中国海洋湖沼学报》2005,23(1):43-47

According to the data of main environmental factors and the depth of localized corrosion of carbon steel and low alloy steels in China seas, combined with the result of grey interrelation analysis, double-factor method was proposed to evaluate and classify seawater corrosiveness. According to the temperature of seawater and the biologically adhesive area on steels, the corrosiveness of seawater from low to high level is classified into five levels （C l-C5）, which was identified by the data of corrosion depth of carbon steel immersed in water for one year.  相似文献   

广东省新丰江流域4—5月暖云的微物理特征   总被引：7，自引：1，他引：6

本文对新丰江流域初夏暧云的含水量与小云滴谱特征进行了分析。指出暖积云的含水量比暖性层积云大;广东初夏暧性层积云的含水量大于北方降水性As—Ns云系。被探测云的主要降水机制均为碰并增长过程,但浓积云中云滴碰并增长条件比层积云优越;与湖南等地积云相比,广东积云更具有海洋性积云的特征。   相似文献
