船用配电柜承重梁结构优化设计

Structural optimization design of marine electrical cabinet bearing beam

针对船用配电柜受到外部冲击可能发生功能失效这一现象,对船用配电柜承重梁结构进行优化设计,在符合规定的外形尺寸与重量范围内通过优化设计增强结构的抗冲击性能。采用有限元法对四种不同结构的承重梁结构进行抗冲击仿真计算,得到相应的抗冲击响应应力和变形。通过对比分析得到在相同重量下,抗冲击性能最强,性价比最高的配电柜承重梁结构型式,可以为同类型的配电柜承重梁结构设计提供参考。

Aiming at the phenomenon that the function failure of the marine electrical cabinet may occur due to external impact,the bearing beam structure of the marine electrical cabinet is optimized,the impact resistance of the structure is enhanced by optimizing the design within the specified size and weight range.The impact response stress and deformation of four kinds of bearing beam structures are calculated by finite element method.Through comparative analysis,the structure type of Marine electrical cabinet bearing beam with the strongest impact resistance and the highest cost performance under the same weight is obtained,which can provide reference for the structure design of the same type of Marine electrical cabinet bearing beam.
