摘要
以高速旋转的储能飞轮为研究对象,以优化飞轮的性能为目标,针对其结构特点,利用ANSYS Workbench软件建立了有限元模型,对储能飞轮进行了应力分析,得到其最大径向应力和环向应力.在此基础上,对储能飞轮6个关键尺寸进行了优化分析,以飞轮质量和最大变形量最小为目标函数,进行飞轮的特征尺寸优化设计.优化后的方案与原设计方案相比,质量减小了8.54%,最大变形量减小了2.87%.分析结果将为储能飞轮的结构设计和优化提供重要参考.
In order to optimize the performances of the flywheel,the finite element model was established based on ANSYS Workbench software.The stress analysis of the flywheel was carried out to obtain the maximum radial stress and the maximum circumferential stress.On the basis of the analysis,the key six dimensions of the storage flywheel are optimized and analyzed with the flywheel mass and the maximum deformation amount as the objective function,and the characteristic size of the flywheel is optimized.Compared with the original design scheme,the mass and the maximum deformation of the optimized scheme are reduced by 8.54% and 2.87% respectively.The analysis result will provide an important reference for the structural design and optimization of the energy storage flywheel.
