Design and Analysis on KTX Reversed Field Pinch Device Main Support Structure

摘要: KTX反场箍缩实验装置主支撑由柔性支撑和支撑平台组成，主要用来支撑真空室、导体壳和纵场线圈的重量。鉴于主支撑结构的重要性，通过有限元分析和理论分析相结合的方法对主支撑进行了强度分析和稳定性分析，给出了主支撑应力分布和变形情况及不同结构参数下的临界载荷。分析结果验证了主支撑结构的可行性，并为主支撑的后续优化设计提供理论依据。

Abstract: KTX reversed field pinch experimental device main support is composed by the flexible support and support platform, and mainly used to support the weight of vacuum chamber, the conductor casing and the toroidal field coil. In view of the main supporting structure’s importance, the main support stress distribution and deformation and critical load under different structural parameters were obtained through finite element analysis and theoretical analysis on the main support for the strength analysis and stability analysis. The results demonstrate the feasibility of the main supporting structure and provide a theoretical basis for subsequent optimization-based support.
