摘　　要：利用集中参数法建立了燃气轮机模型,并计算其模态。将集中参数法和有限元法计算的燃气轮机模态相比较,发现两种方法的前两阶模态相一致,从而得出结论:集中参数法可用于燃气轮机建模和计算。The model of a gas turbine was established by the lumped parameter method, and the modal was calculated. The results of the lumped parameter and the finite element method were comprised, which found that the first two modes of the two methods are consistent. It＇s concluded that the lumped parameter could be used for gas turbine modeling and calculation.

关 键 词：燃气轮机 集中参数法 有限元法 模态 建模
