摘　　要：针对振荡浮子式波浪能利用技术,提出一种单浮筒式波浪转换设计方案,对单浮筒随波浪的运动特性展开研究,将波浪能转换为振荡浮筒的摆动机械能,传递给PTO能量转换系统。通过采用Star-CCM流体仿真软件分析浮筒装置在不同PTO能量转换系统参数下的运动特性及受力情况,得到不同弹簧阻尼工况下浮筒装置的运动特性,以期为波浪能技术的装置结构优化及真实海况运行提供理论基础。To improve the technology regarding oscillating float-type wave conversion,a single buoy wave power device was proposed.Motion characteristics of a single buoy on the waves were studied. Wave energy was converted into oscillating mechanical energy of the oscillating buoy,and transmitted to the PTO system(energy conversion system). By CFD method(Star-CCM Software)to analyze the motion and load changes of the buoy under different conditions of the PTO conversion system,motion characteristics of the buoy with different damping parameters were acquired. The results provide a theoretical basis for later optimization of the device and actual sea tests.
