水下行车水阻力研究

Study of Water Resistance of Underwater Travelling Crane

测磁行车的主结构位于水下 ,运动时将受到很大的水阻力。阻力模型试验技术是研究阻力问题和处理实际工程问题的重要手段和方法。二维截面模型试验和行车整体模型试验确定了行车主截面的形式 ,并得到了各种速度下的水阻力。

The main frame of a travelling crane for measuring magnetism is dipped underwater.The frame stands great water resistance while its moving.To make experiment with model is one of the most important means to study the resistance problem and to solve practical problem in projects.In this paper,the main cross-section configuration of the frame is determined by experiment of a two-diension cross-section model and by experiment of the whole model of the crane.Meanwhile,the magnitude of water resistance is measured at various travelling velocity.
