The paper describes further ongoing work on a new complex system for measuring and calculating the vibrations of turbine blades which was introduced in previous publications. This new system uses an innovative approach consisting of precise separation of measured data. The following text relates to the method of calculating the pure blade vibration based on an analytical approach. It is an essential part of the complex system. For this purpose, the multiple analytical method was developed and named “Anmena” (it is an abbreviation of the Czech term “analytická metoda” násobku, meaning analytical method of multiple). This paper is focused on introducing the basic principle of method and analysis of its reliability and expected accuracy on theoretical aspects. In addition, the so-called zero deviation axis is introduced for solutions that are theoretically independent of the distortion of the measured data expected in practice.
