本文主要研究热套盘鼓式转子的振动特性,并以4000马力机车燃气轮机转子作为对象进行研究。文中对七种不同类型的模型转子及实物转予进行了试验和计算。研究表明,剪切变形和热套联接处的刚度影响是不容忽视的,尤其是后者影响更大。为了考虑热套联接处的刚度影响,引入了刚度修正系数,在计算中,考虑了上述二者的影响后,使转子一阶固有频率的计算值与动试验的实测值比较吻合。有关计算方法可供设计该类转子时参考。 In this paper, we mainly study the vibration characteristics of the drum rotor with a heat-set of 4000 horsepower and take the gas turbine rotor of 4000 horsepower locomotive as an object. In this paper, seven different types of model rotor and physical transfer were tested and calculated. The research shows that the influence of shear deformation and the rigidity of the joint at the thermowell can not be neglected, especially the latter is more influential. In order to consider the influence of the rigidity of the joint at the thermowell, a stiffness correction coefficient is introduced. After considering the influence of the above two factors, the calculated value of the first-order natural frequency of the rotor is in good agreement with the measured value of the dynamic test. The calculation method for the design of this type of rotor reference.
