摘　　要：以单圆柱能量转换装置俘能数学模型为基础,构建多圆柱涡激振动能量转换数学模型及多个能量转换器阵列优化布局数学模型。为提高阵列优化效率,首次以俘能功率为目标,采用基于遗传算法的分层优化算法对多个俘能装置进行阵列优化布置研究。在4 m×4 m海域内,分别对2、3、4、5、6、8个能量转换装置阵列布置进行优化计算;通过流固耦合数值模拟方法,对3个俘能装置阵列优化结果进行验证,以分析相互作用因子q的变化规律。结果表明:该优化算法可有效优化多圆柱俘能装置阵列布置,优化后的布置增强了阵列中各装置间的相互作用,显著提高了多圆柱涡激振动俘能装置阵列的发电效率。The large-scale deployment of energy converters for harvesting low-velocity ocean current energy by vortex-induced vibration(VIV)is bound to become the inevitable trend to develop low-velocity current energy with large scale.In this study,based on the mathematical model of energy capture of single cylindrical energy conversion device,the mathematical model of energy conversion of multi-cylinder vortex-induced vibration and the mathematical model of optimal layout of multiple energy converter arrays are constructed.In order to improve the array optimization efficiency,aiming at the energy capture power for the first time,the hierarchical optimization algorithm based on genetic algorithm is used to study the optimal layout of multiple energy converters.In the 4 m×4 m sea area,the array arrangements of 2,3,4,5,6 and 8 energy conversion devices are optimized respectively,and the optimization results of three energy capture devices are verified by fluid-structure interaction numerical simulation method.in order to analyze the variation law of interaction factor q.The results show that the optimization algorithm can effectively optimize the array layout of the multicylindrical energy converters,and the optimized arrangement enhances the interaction between the devices in the array and significantly improves the power generation efficiency for the multi-cylindrical energy converter.
