摘要

为实现透平动静部件耦合振动特性的快速分析

将包含透平气缸和支架直接刚度、串扰刚度的机械阻抗作为计算边界

使用改进传递矩阵法对重型燃气轮机透平试验件进行了模态分析和不平衡响应分析

并且与有限元分析结果和试验数据进行对比分析。结果表明:相比于试验数据

改进传递矩阵法和有限元法分析得到的转子临界转速偏差分别在-3.38%~2.31%和-6.08%~7.05%

改进传递矩阵法得到的临界转速更接近试验值

有限元法得到的最大响应峰值更接近试验值

计算得到的振动响应曲线与试验结果趋势基本一致。考虑机械阻抗的改进传递矩阵法能够快速准确获取透平转子的临界转速及整机振动响应特性。

Abstract

To achieve the rapid coupling analysis of the vibration characteristics of the rotating and stationary components of turbine

taking the mechanical impedance including the direct stiffness and crosstalk stiffness of the turbine casing and support structure as calculation boundary conditions

researches were carried out on modal analysis and unbalanced response analysis for of heavy-duty gas turbine test component by the developed transfer matrix method

while comparisons were conducted on above method results

finite element method results

and experimental data. Results show that

compared with experimental data

the deviations of critical speeds of the rotor obtained by the developed transfer matrix method and finite element method are within -3.38%-2.31% and -6.08%-7.05%

respectively. The critical speed obtained by the transfer matrix method is closer to the experimental value

while the maximum response peak obtained by finite element method is closer to the experimental value. Meanwhile

calculated vibration response curves are basically consistent with experimental results. The developed transfer matrix method incorporating mechanical impedance can quickly and accurately obtain the critical speed of turbine rotor and the vibration response characteristics of entire unit.
