【摘要】 针对某风电储能用大型箱式变电站体积庞大、吨位重、载荷分布不均匀等特征可能引发的箱体底座变形、开裂问题，对其开展起吊强度分析与结构优化。基于Ansys Workbench分析平台，建立底座起吊模型，分析底座变形和应力，通过减少型材数量和降低型材规格优化底座结构。结果表明：原始设计方案过于保守，强度安全裕度过大，成本较高，通过结构优化，保证箱体强度，同时实现底座减重24%，降低材料成本。所优化设计的大型集装箱式变电站底座强度满足要求，实现了安全起吊。更多还原

【Abstract】 In view of the potential deformation and cracking of body base of a large container-type substation used for wind power energy storage due to its large size,heavy weight and uneven load distribution,a lifting strength analysis and structural optimization are conducted.Based on the Ansys Workbench analysis platform,a base lifting model is established to analyze base deformation and stress,and the base structure is optimized by reducing the profile quantity and lowering profile specification.The results show that,the original design plan is overly conservative,with excessive strength safety margins and high costs,and through structural optimization,the body strength is ensured while achieving a reduction of24% in base weight and lowering material costs.The trial production results show that the base strength of the large container-type substation after optimization design meets the requirements and achieves safe lifting.更多还原
