Study Of Wave-Making System And Wave Simulated Technology In The Towing Tank

At present, the seakeeping experiment of shipmodel is a regular test project in the shipmodel towing tank laboratory in our school. So, the capability of wave-making system of towing tank becomes the linchpin upon which undertake to test. For improving the make-wave system function, widen wave simulation form , raise wave simulation quality, We have this paper.First, this paper introduces the basic theories of wave and calculation principle. We have made a full theoretical analysis of the wave property and the wave parameters of the flap-type wave generator in the towing tank of our school, and confirmed that should make the factor that the performance of the wave generator give play to normally to influence. In allusion to that the old wave generator can not simulate sea wave, upgrade and transform to this system change the control computer system and install additional D/A change card, redesign the wave control interface and transmission means of control signal, give up the disk machine that can not be used, make the wave-making control voltage signal that has translated direct input the wave controller, make wave controller to make waves through servo system. The paper also utilized VB and Visal Fortran two kinds of programming languages and worked out waves of making and control the software again, This software is operated under windows operating system, way to operate through the menu , can be finished producing from the wave signal data file under a window, make wave control, spectrum analyse and wave machine initialize and parameter person who set up work to data thatgather, It is simple and convenient to operate.Finally, the paper introduces the test of wave simulation by wave-making system that has improved.the test data indicate that it is able to competent at wave simulation of sea wave spectrum for shipmodel test, we have changed the situation that the wave-making system can't simulated sea waves. And have established the foundation for the quality of improving the scientific research of our school and experiment teaching further.
