The Dynamic Analysis of the Green Anode Processing Building

Article presents the dynamic analysis of the green anode processing building at Slovalco company in the city of Žiar nad Hronom. The production process contains anode cauterization, and then this anode is put into the air furnace and consumed during producing the primary aluminium by electrolytic process. Anodes are made of calcined petrol - coke and tar. The processing building is built as the steel frame structure, which contains steel girder platforms. The dynamic analysis contains two base steps, and that is the FEM model of the entire construction and the experimental measuring. The FEM model was created via software Scia Engineer vs. 2015. The FEM model comprises elements with designed dimensions of cross sections due to final design documentation. The platforms were modelled as the girder structures. Computing run was done via modal analysis. There were ten natural frequencies and ten modes of natural vibration as the results, in quite low frequency band. Six experimental measurement series were realized. The principal aim of dynamic response experimental measurements was detecting the vibration intensity of machines and the vibration frequency band of machines. These machines are in closeness to the restroom that is why the dynamic response of them was investigated. The vibration intensity was measured with the aim of checking the vibration effects on humans and on building structure.
