| 摘 要： | 催化裂化装置中烟气轮机入口管线结构十分复杂，按常规强度设计法难以准确计算，应用有限元计算法对该管系结构、热胀应力和自重应力进行了系统分析。根据计算结果指出了该管系失效原因，并提出了改进措施，实际计算表明，用有限元法可以较准确地算出管系的位移和内力，从而得到更合理的设计方案。

| Abstract: | The structure of inlet manifold in flue-gas-turbine of fluidized catalyst crackingunit is complex. It is difficult to obtain an accurate calculating result for the inlet line byusing the normal design method. This paper presents a calculation example with finite elementmethod. The failure reasons of the inlet line can be found from the calculating results. Someimprovements for the inlet line were proposed. |
