The Optimization Of Floating Wave Energy Converter Based On The Study On Hydrodynamic Performance

The ocean which covers nearly 71 percent of the Earth's surface.The ocean contains abundant resources about plants,minerals,and clean renewable energy that is almost inexhaustible.Facing the energy crisis,all the countries in the world have stepped up the pace of exploration of marine resources.Wave energy has become one of the most promoting types because of its reserves and distribution.A variety of wave energy can also be used to change the device from the previous theoretical assumptions slowly become a reality,With the marine resources of the world powers have been successful in offshore built a variety of wave energy conversion equipment.As a third generation wave power generation device,the floating wave energy transfer device is being researched and produced by more and more research institutes and manufacturers.According to the China sea conditions with floating wave power device carries on the analysis and optimization of deployable structure,for on this kind of device has important significance.This article mainly from the following aspects:First of all,explain the research background and significance of the research,this paper introduces the structural characteristics of several kinds of wave power generation device and the advantages and disadvantages and thus leads to the research content,then expounds the research status and development trend of domestic wave power generation device,and introduces the topic and put forward the main research contents and methods.Secondly,After the composition of main research topic selection of floating wave power device structure and working principle of the device are introduced in detail,the core of the device is to rely on the float wave absorption can produce relative motion through the energy conversion to achieve power generation and buoy.According to the characteristics of the device with the characteristics of Chinese ocean sea conditions in Shandong province were selected into the waters near the Rongcheng mountains assumed place of work for the device,convenient after the study.Then,this paper from the linear wave theory to analyze the wave force by the device,and then used the ANSYA software to simulate the stress and strain on the device body force is analyzed,the main research under the action of waves is mainly affected by the wave body float under wave force lateral force on the buoy.Finally,investigation and analysis of anti wave measures on ocean engineering used in the hole,on the waves and perforated double cylinder of theoretical basis and put forward the opening device optimization scheme,then the simulation research on hydrodynamic device using AQWA commercial software,validity hole optimization scheme,to improve the wave resistance optimization verification device.
