Parameter Optimization Design and Power Response Analysis of Oscillating Buoy Wave Energy Converters With Random Loads
摘要
Abstract
The oscillating buoy wave energy converter is a kind of core working unit of wave energy power gen-eration system,and its development is of significances for breaking the power supply bottlenecks in coastal are-a development and offshore platform construction of in China.Then the coupled motion model for multi-DOF wave energy conversion structures was built to investigate its mechanical configuration,parameter design and energy capture mechanism.Through optimization of the intelligent algorithms such as the particle swarm algo-rithm,the problems of the too large multi-DOF iteration scale and the local optimal solution dilemma were o-vercome,the functions of the algorithm were enriched,and the oscillation and energy capture effects of the wave energy converter based on 2D/4D,linear/nonlinear damping and structure dimension parameters in 2 sce-narios,were qualitatively and quantitatively evaluated.The capture energy advantages of vibration control con-ditions of multi-DOF and nonlinear damping,were verified,and the dynamic behavior law,the parameter opti-mization design and the efficient path of energy capture mechanism were explored simultaneously.Random loads were introduced to optimize the accuracy of the model,and the effects of noise differences on the energy capture were refined.The work provides a new idea for the effective application mode of wave energy conver-sion structure in practical engineering.关键词
