Abstract:

According to ITER device requirements for cryostat feed through(CFT) technical characteristic and special low temperature and high vacuum environment under feeder systems working condition, taking heat conduction and radiation heat transfer into account, adopting finite elements analysis, feeder systems were engaged in steady state thermal analysis, transient thermal analysis, coupled analysis between structure and heat conduction. The temperature distribution, heat leakage, temperature-time curve and deformation time cure can be obtained, which offer the basis for the design and the improvement of CFT.

摘要：

根据ITER装置对过渡馈线技术性能的要求及馈线系统工作时所处的特殊低温真空环境，考虑热传导和辐射换热等因素，采用有限元分析法对过渡馈线系统进行了稳态热分析、瞬态热分析、温度-结构耦合分析，获得了过渡馈线的温度分布、系统热漏、温度及变形的时间历程曲线，为过渡馈线的设计和改进提供了依据。
