During shaker tests to determine the strength properties of the test article, it can be difficult to shake the article to the required in the concentrator stresses. This may be due to the losses of the force transmitted from the shaker to the test article, which occur due to an improperly designed rig. Using some methods for rig designing, along with numerical modeling, provides the possibility to make an easy-to-excite rig with minimum loss of transmitted forces. This paper deals with the modeling of the “article – rig – shaker” system executing constrained oscillations under the influence of harmonic excitation. The model’s response dependencies on dynamic excitation caused by the oscillation frequency have been outlined. The excitation level’s influence on the dynamic parameters of the model have been analyzed.
