【摘要】:运用ANSYS对冷却管进行有限元热应力分析,研究了在大温差下其热应力分布情况,通过分析得出冷却管在66.5℃大温差条件下满足受力要求的结论,并对结果对比可知冷却管内外压力对热应力大小无影响,为实际工程的运行和设计提供了理论指导,也填补了国内凝汽器冷却管大温差热应力研究的空白。
[Abstract]:The finite element thermal stress analysis of cooling tube is carried out by using ANSYS, and the distribution of thermal stress under large temperature difference is studied. The conclusion is drawn that the cooling tube can meet the stress requirement under the condition of large temperature difference of 66.5 鈩,
