Study of the Compensation System For Nonlinear Distortions in Vibration Tests With a Fixed Frequency

The article is devoted to the study of the parameters of the dynamics of the moving part of an electrodynamic shaker with a fixed mass. A mathematical model of an electrodynamic shaker is considered. A study is conducted to identify harmonic distortions with different loads of the vibration table. The article considers the structural diagram of the vibration test system and the diagram of the proposed solution. The operability is checked and the result of the compensation system operation in laboratory conditions is given. The distortion coefficient was reduced to $\mathrm{2. 4 \%}$.
