摘要
通过有限元方法对充满低温液体的气瓶进行传热分析,与试验的结果相结合,分析气瓶的颈管、支撑结构和绝热结构的漏热量并对产品结构进行优化设计,来保证达到优良的绝热性能。
For the favorable heat insulation performance, the heat transfer of cylinder full of cryogenic liquid was analyzed by finite element analysis method and the calculation results conformed to the results of experiments. The heat leak through neck tube, supports and insulated structure of cylinders were also obtained to achieve an optimum design for the structure of products.
