INFLUENCE OF OWN FREQUENCIES
ON THE PLANE TRUSSES
In the paper is presented the way in which the own frequencies influence the good functioning of the plane trusses. The four types of trusses: Howe, Pratt, Warren with and without vertical beams were built and modeled with finite elements using the SolidWorks program. The experimental analysis was carried out on the particular stand developed for this kind of trusses. For the acquisition and processing of data, I use Kistler accelerometers and the LabVIEW program.
