摘要
大型海洋垂直轴风力机的研究对发展海洋风能具有重要意义,研究大型垂直轴风力机的合理支撑结构形式对风力发电结构安全至关重要.基于变删除率的双向渐进结构优化(BESO)算法,对大型海洋垂直轴风力机进行支撑结构优化,并通过风力机的动力响应特性分析,验证结构优化方法的可靠性.结果表明:反比例型变删除率的BESO算法能有效改善优化迭代速率,适用于垂直轴风力机的支撑结构优化设计;相比于初始结构,拓扑出的新结构模型在风荷载作用下的风致动力响应显著降低.研究成果可用于垂直轴风力机支撑结构设计优化.
The research on large-scale offshore vertical axis wind turbine is of great significance to the development of ocean wind energy.For the safety of wind power,it is very important to study the reasonable supporting structure of the large-scale wind turbine.In this paper,an supporting structure optimization of a large-scale vertical axis wind turbine based on the variable deletion rate bidirectional evolutionary structural optimization(BESO)algorithm is proposed,and the reliability of structural optimization is verified by analyzing the dynamic response.The results show that this inverse proportional BESO algorithm can effectively improve the optimization iteration rate,and has a wide applicability to the optimal design of vertical axis wind turbine supporting structure.Compared with the initial structure,the wind-induced dynamic response of the topological new structure model under wind load is significantly reduced.The findings can be used to optimize the structural design of vertical axis wind turbine.
