| Abstract: | 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 ... |
