Title Study on attitude stabilization of floating platform Wave Model Establishment and Simulation
Abstract
This paper is a basic research for the attitude stability technology of the floating
platform.The sea wave has a great influence on the movement and attitude of the
floating platform,so the attitude stability of the floating platform has a lot
to the marine environment.For the further research on the floating platform
attitude stabilization technology,first of all we need to research the response
of the floating platform to the wave ,which need to understand the characteristics
of the wave itself and establish the mathematical model of the waves.The emphasis
of this paper is on the study of the characteristics of the waves,and the
mathematical model of random ocean waves based on the relevant wave theory.Based
on the establishment of the wave mathematics model,the numerical simulation of 源￥自%六^^维*论-文+网=www.lwfree.cn
the waves by MATLAB is carried out. Through simulation,the rationality of the
establishment of ocean wave model is verified firstly;secondly,form the simulation
results intuitively understand the wave characteristics,and contact the water
surface floating platform,the application of ocean wave model is proposed.
