摘要
低温容器是超导电动悬浮列车的核心部件,其支撑杆的设计应兼顾高结构强度和低漏热这两个关键因素.然而,增加支撑杆结构强度往往会导致高漏热,这将不利于列车安全运行.为了解决这一问题,本研究针对低温容器的支撑杆,以满足结构强度前提的同时获得最小的传导漏热为目标,对不同支撑方式下的支撑杆内外径及杆长进行了优化.优化结果满足设计要求,实现了支撑杆结构强度与漏热量的平衡,为试验样机设计提供了理论参考.
Abstract
The cryostat is the core component of the superconducting electrodynamic suspension train,and the design of its support rod should take into account two key factors:high structural strength and low heat leakage.However,increasing the structural strength of support rod often leads to high heat leakage,which isnt conducive to safe train operation.To address this is-sue,this study aimed to optimize inner and outer diameters and length of support rod under different support methods,with the goal of achieving minimal conduction heat leakage while meeting the structural strength requirement.The optimization results meet the design requirements and achieve the balance between structural strength and heat leakage of support rod,providing a theoretical reference for the design of test prototype.
