Optimization of support structure for on-board cryostat in electrodynamic suspension train
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.
