This article presents the way to obtain the structural model for elementary linear-elastic static analysis of equipment to prepare the germinative bed in strips main resistance structure. Also, to prove the functionality of the structural model obtained, the structural analysis results for the linear elastic static test are presented. These results are useful for estimating the safety factor and for assessing the behaviour in major overstress situations at the main part of the machine. Structure dynamics is a very broad discipline that uses a huge arsenal of theoretical and experimental methods to solve a fundamental problem of structures: the dynamic response to variable tasks over time. Vibrations, and especially vibration in resonance modes, are problems that occur frequently in large structures. As large structures with large numbers of components cannot be optimally engineered for resonant regimes, it is often done to resolve structures or improve them by using the modal analysis of the mathematical models of these structures. The usefulness of this analysis is particularly evident in the testing phase and even in the first stages of operation, when it is necessary to improve the working regime of a product of the type analyzed. The main results of the static linear-elastic structural analysis are: the values of the reactions in the holders, vector field distribution of the relative – resultant displacement in the structure, tensor fields’ distribution of the specific deformation and the Cauchy stress tensor in the same structure. Also, an important result for the structure safety is the distribution of the safety factor. The analysis of the equipment’s own spectrum allows proper identification of the main frequencies, at which a resonant working regime can occur.
