摘要
分别建立了装实心和空心传动轴动力涡轮转子动力特性的有限元分析模型,对2种情况的转子动力特性从理论上进行了系统的计算分析,并在试验器上对动力涡轮转子的临界转速等进行了验证。
The dynamic characteristics models of power turbine rotors with solid and hollow transmission shafts are set up respectively by using the finite dement method. The dynamic characteristics of the two types of rotors are systematically calculated and analyzed in terms of theory. The critical speed and some other problems of the power turbine rotors are demonstrated on the test rig. The results have shown that the model can veritably reflect the dynarnic characteristics of the rotors.
