一种大型设备方舱结构设计与分析

Design and Analysis of Structure of a Large Equipment Cabin

随着设备小型化发展,方舱内设备对散热要求越来越高。采用液冷系统能有效提高散热能力,但冷却系统质量大,对方舱结构的刚度和强度要求高,特别是在方舱吊装状态下,是该种方舱使用过程中的危险工况。该种类型的方舱在设计过程中应当对承载区域进行重点分析,并结合有限元方法,进行仿真验证,提高设计效率。针对某型设备方舱的布局特点,在结构上进行了针对性设计,对于载荷较大的区域进行了局部加强,并在合理简化的前提下建立了方舱舱体骨架的有限元模型,采用有限元方法对舱体结构的刚度和强度进行了分析。分析结果显示,该型方舱结构设计合理可行,同时说明有限元方法在结构设计中具有较强的指导意义,也说明有限元方法能有效提高设计质量。

With the development of miniaturization of equipment,the equipment in the cabin has higher and higher requirements for heat dissipation.The liquid cooling system can effectively improve the heat dissipation capacity,but the cooling system had a large weight,and the rigidity and strength requirements to the outer cabin structure were high,especially when being hoisting state of the cabin,which was a dangerous working condition in the use of the cabin.This type of cabin should focus on the load-bearing area during the design process,and combined with the finite element method to verify the simulation and improve the design efficiency.The layout characteristics of a certain type of equipment cabin were designed in a targeted manner,the area with large loads was partially strengthened,and the finite element model of the cabin skeleton was established under the premise of reasonable simplification.The stiffness and strength of the cabin structure were analyzed by finite element method.The analysis results showed that the type of the cabin was reasonable and feasible,and the finite element method had a strong guiding significance in structural design,it also showed that the finite element method can effectively improve the design quality.
