深拖系统中缆运动的力学特性

Dynamic Performance of the Cable Used in Deep Towing System

在深拖系统动态分析的基础上，研究了收放缆及垂荡运动中拖体的运动响应及缆端点处的张力变化．得到的张力变化趋势，为深拖系统设计中缆的选择提供了依据．关于拖体对收放缆及垂荡运动响应的研究，有助于在使用过程中预报拖体的运动响应，指导实际操作．

A deep towing system is studied based on dynamic analysis.The main idea is to study the strain change in a cable as the vehicle is in response to draw in and let out cable,and to heaving as well.The change tendency of the strain along the cable is given,which can be used in guiding the selection in cable designing.Also,the research of dynamic motion of the system can be used in guiding the practical operation.
