用有限元分析方法模拟了200 L LNG气瓶容器在稳态导热情况下的整体温度场分布，并对不同充满率下的漏热量进行了计算，漏热量的计算结果与文献中的试验结果一致，说明本研究方法切实可行。根据内容器高径比H／D的不同对气瓶结构进行优化，计算结果表明：在相同充满率下，高径比H／D越大，漏热量越小。

We simulate the 200L LNG cylinder under steady-state thermal conditions by using the finite element a-nalysis and get the whole temperature distribution.The heat loss under different filling rate is also calculated and the results are consistent with experimental results in the literature, indicating that our method is feasible.The cyl-inder structure is optimized according to different height-to-diameter ratio of the container.Our results show that under the same filling rate, the greater the height-to-diameter ratio, the smaller the heat loss.
