涡轮盘是燃气轮机的关键部件,在服役过程中承受着极高的离心载荷、振动载荷和热负荷,极易失效破坏。从流程分析的全局出发,明确了不同模块的输入输出元素,建立了燃气轮机的研发流程构建方法。在此基础上以涡轮盘为研究对象,针对其典型载荷,建立了基于ABAQUS的涡轮盘强度分析流程;针对其典型失效形式,建立了包含多种试验的涡轮盘寿命分析流程;明确了强度分析和寿命分析支撑要素,并分析了要素之间的关联关系。

[Abstract]
The turbine disk is a key component of gas turbine,which is subject to very high centrifugal load, vibration load and thermal load during service and is easily damaged. Based on the overall situation of process analysis, the input and output factors of different modules are defined, the research and development process construction method of gas turbine is established, on the basis of which the turbine disk is the research object, the turbine disk strength analysis process based on ABAQUS is established according to its typical loads, the turbine disk life analysis process including various tests is established according to its typical failure mode, the support factors of the strength analysis and life analysis are clarified, and the correlation between the factors is analyzed.
