Turbomachine blading vibrations are one of the most important problems. They are the reason for turbine damages. Numerical methods of vibration analysis are useful in prediction of the frequencies, the distribution and localisation of stress in blades. Accordingly, in this work numerical methods and results of computations are performed for various types of blading.
