摘要
该文以同轴双浮体波能装置为研究对象,以山东省波浪场资源为背景进行条件,首先提出Matlab-APDL-AQWA联合仿真系统,实现波能-功率全过程模拟,并将模拟结果与文献中的物理模型试验数据进行对比验证.同时探究随机波浪作用下浮体半径、质量参数及PTO参数对装置获能平均功率的影响.研究表明,双浮体的半径参数和质量参数会显著影响装置的平均功率,装置获能随PTO阻尼系数的增大呈先增后减的趋势,而PTO刚度系数在一定范围内变化对装置获能影响不明显.
Abstract
Taking the coaxial two-body wave energy converter(WEC)as the research object and the wave field resources in Shandong Province as the background conditions,This paper first proposes the MATLAB-APDL-AQWA joint simulation system is proposed at first,through the secondary development of Python,the effect of PTO damping is considered to realize the full process simulation system to realize the full process simulation of wave energy-power,and compares the simulation results with the physical model test data in the literature.At the same time,the influence of floating body radius,mass parameters and PTO parameters on the average power of the device was investigated under random wave conditions.The research shows that the radius parameters and mass parameters of the two-body will significantly affect the average power of the device,and the energy gain of the device will first increase of the PTO damping coefficient,while the change of the PTO stiffness coefficient within a certain range has no obvious impact on the energy gain of the device.
