摘要

对横向流作用下的海洋地震拖缆进行姿态控制仿真研究.在现有理论基础上,建立拖缆三维集中质量模型,列出节点控制方程,结合边界条件,推导出控制方程的数学表达式;采用Newton迭代法求解非线性方程组,并在MATLAB中编写求解程序,获得典型工况下拖缆姿态图.在此基础上,引入嵌入式"水鸟"对拖缆姿态实施主动控制,获得主动控制下的拖缆姿态,旨在为海洋地震拖缆的姿态控制提供理论依据.
This paper studies the attitude control of marine seismic streamer under the action of transverse flow.Based on existing theories,a three-dimensional lump-mass model is set up,and the governing equations is listed and the mathematical formulations is derived after considering boundary conditions.The established nonlinear equations are solved by using Newton iteration method and the figure of the streamer attitude under a typical operation condition is obtained.On this basis,embedded birds are introduced to implement active control on the streamer and the streamer attitude under active control is obtained,which can provide theoretical directions for the attitude control of marine seismic streamer.
