The Comparison of the Modal Analysis of a Membrane Structure
Štulerová, Lenka ; Kapolka, Lukáš ; Kmeť, Stanislav
This article deals with the comparison of the results of a natural oscillation. It is a membrane, which in one case represents a solitary, articulated structure, in the other case this structure is anchored to a steel frame. In general, boundary conditions are simplified in the calculations, but in dynamic specifically these approximations can negatively affect the results. Therefore, the first variant presents a simplified form and the second variant more accurately complements the real model. The observed characteristics are the basic dynamic parameters: natural frequency, natural period. The aim of this paper is to compare the influence of the secondary structure forming the support system on the overall stiffness, which can significantly contribute to the results of dynamic analyses.
