中日海底光缆埋设犁研制

The Design and Manufacturing of Burying Plow for Sino-Japan Subsca Optical Fibre Cable

埋设犁设计中的两个主要问题,一是如何减小埋设犁的阻力;二是埋设犁在海底运行的稳定性。本文对前者提出了大后掠角犁翼设计思想,对后者则讨论了犁刀曲面各参数及入土角的选择。

There arc two main problems in the design of burying plow,the first one is how to reduce the resistance of the plow,the second is how to keep the stability of the plow when it moves on the sea bed. For the former one,the design philosophy of large sweepback angle of plow blade is introduced and for the latter one,the selection of earth entry angle and the parameters of the curvature of the plow arc discussed in this paper.
