Abstract: The article discusses the study of the elastic system dynamics for spindle assembly of drilling-milling-boring machining center type. A threedimensional model of the spindle assembly on rolling bearings is built. A constructive and design diagram of the spindle assembly and a system of forces acting in the process of milling workpieces are formed. The statement on the polyharmonic nature of the input power effect change during the milling process is substantiated. The phenomenon of modeling disturbing effects by superimposing a “white noise” type random component in the MatLab software environment is investigated. The synthesized input signal and its spectral density using the method of Fast Fourier Transform in a Signal Processing environment are obtained. The concept of the spectral windows for increasing the information content of the obtained dynamic characteristics and reducing the variance of frequency estimates is analyzed. The selection of the best spectral window is carried out, with the help of which the distortion of spectral estimates is minimized.
